Congratulations mama: baby number two is on the way! 

Expecting baby number two can be so exciting and intimidating at the same time. There’s the joy of bringing a new life into the family and a sibling for your older child while you’re also likely feeling a bit anxious about having to juggle two kids at the same time.

I have personally been there: I have two kids who are 2.5 years apart. Even though I know everyone’s situation is a bit different, particularly depending on the age gap between the two kids, looking after two children at the same time is always full on!

Getting prepared for the arrival of the new baby and making sure you have everything you need to tackle this next stage of motherhood will definitely help you feel equipped.

That’s where this second baby registry checklist comes in! It includes the items you can reuse from your first baby, the items to buy brand new, and some handy extras to make your life easier.

You’ll need to check everything that you’ve kept from your first child and make sure you can still use it, buy anything else you are missing, but also think of any extra items that will make your life easier.  

I’ve included the best gear for your second baby, including what to buy for second baby even if it’s the same gender.

Should I Create a Registry for Second Baby?

I think second time moms should always create a gift registry for their second baby. It’s a great way to keep track of the items you’ve deemed as second-time mom must haves and if friends or family members are wondering what to buy for a second baby gift, it gives them plenty of ideas for things you actually need.

Plus, there are plenty of perks for setting up a new baby registry!

Most of the items listed below are perfect to add to your second baby registry.

To make it easier for you, I have split the checklist into 3 different sections:

  • Must Haves: these are must-have items that you definitely need to buy new and you can’t reuse from your first baby, either for sanitary or safety reasons, or simply because you just need to re-stock them.
  • To Make Life Easier: these are not absolute essentials (you can survive without them), however they will make your life so much easier if you can afford them.
  • Things to Check: these are items that you may or may not be able to reuse from your first child, so look them and over and assess.

Must Haves for Second Baby

1. Diapers

Diapers are a perfect item for your second baby registry! Unless you are using cloth diapers and the ones from your first child are still good enough to be used for your second baby, you’ll need lots of new diapers for your second baby.

I have been using cloth diapers with both my daughters, but not until they were about 4 to 6 weeks old. I use disposables for the first few weeks after birth since they fit so much better. 

Don’t buy too many newborn diapers in advance though. I always recommend only buying about 50 to 100 newborn diapers and then see how big your baby is at birth before buying more. You can register for multiple sizes of diapers and hope that you get a variety to last you through the first year!

2. Wipes

Wipes are definitely another second baby registry must-have. In case you’ve forgotten how many wipes you go through in a day with a newborn, it’s a lot!

You’ll likely use them for diaper changes and cleaning up your older child’s messes so stock up!

3. Other Baby Toiletries

Go through this whole toiletry checklist to make sure you aren’t missing any other toiletries, such as diaper rash cream, body wash, shampoo, nail clippers, etc. 

4. Bibs

I dare anyone who’s having another kid to keep reusing the same bibs from the previous child! This is something that I definitely had to buy new for my second daughter.

The old cloth bibs from my first one were really starting to stink and were falling apart, and the plastic one were half broken by the time my second one was born. Particularly if you feed your baby formula, bibs really start to smell (and look) bad after a while. 

5. Pacifiers / Bottle Nipples

The silicone or rubber in pacifiers starts to break down over time, making them unsafe for baby number two. Pacifiers are a baby registry must haves for sleep, so make sure to add them to your second baby registry!

If you’re going to use the pacifier when baby is awake, register for a pacifier clip to keep it secured to your baby’s clothes, so that you don’t lose it when you’re out and about. You can find a list of the best pacifier clips to choose from here as well as safety standards regarding pacifier clips. 

Just like pacifiers, the material in nipples breaks down over time making them unsafe to re-use for baby number two. Bottle nipples are an inexpensive item for your second baby registry. Get all the nipple flow sizes now that you know how quickly baby moves up a size!

6. More clothes 

If your second baby is a different gender, or is due in a different season than your first, register for outfits to last you through the first year. Luckily, people love buying adorable baby clothes!

7. Nursery Blackout Curtains

Keep your older baby’s blackout curtains up so they don’t start rising with the sun and start good sleep habits with your newborn by creating a dark environment for sleep.

I love the Sleepout Home curtains because they are 100% blackout and they block out light at the top and sides of the window. Use the code POSTPARTUM10 to save 10% off your order.

8. Car seat

The car seat can be tricky as car seats have expiration dates, so it could be unsafe to use the car seat from your first baby with your second one. Make sure to check the expiration date on it before you install it in the car.

Our babies are only 2.5 years apart, so we were able to re-use the infant carseat, but we had to buy a new convertible car seat once the baby got a little older.

9. Car seat mirror

If you are still using a car seat mirror for your older child, don’t forget to buy another one for your second baby as well.

10. Breast Milk storage bags / Pumping Parts

If you plan on pumping and storing milk, stock up on more of these and add them to your second baby must-haves checklist. Check that your breast pump parts are still functioning and in good condition. Inspect them for cracks or build-up of milk residue and replace as necessary.

11. Formula

If you are planning on feeding your baby formula, remember to buy some before your baby is born.

12. Second monitor

I was totally against the idea of buying a second monitor for our second daughter: I really thought we didn’t need it anymore for our first one and that it was going to be a waste of money. That said, I am glad I gave in and that we bought a second one.

It gave us peace of mind to be able to see both our daughters when they were sleeping (or supposed to sleep) in the evening.

Particularly when our oldest daughter went through the two-year sleep regression shortly after her sister was born. She didn’t have toddler bedtime tantrums, but she would get into mischief in her room after we kissed her good night.

13. Double stroller

Lots of moms recommend buying a double stroller when you have a second baby, especially if your two kids are going to be 2 to 3 years apart or even less. We were also really tempted to get one, but then decided not to as our oldest daughter was getting very good at riding next to the stroller with a scooter and we didn’t feel the need.

Another good alternative if you have an older kid who’s not so keen on walking with you and you don’t want to spend a lot of money on a double stroller is a stroller board. This attaches to the back of the stroller and your older child can easily stand on it while you push the stroller.

14. White noise machine

A white noise machine is a baby nursery must have and is especially helpful in drowning out older brother or sister when your baby is trying to sleep. Definitely a second baby registry essential!

To Make Life Easier

15. Bouncer

If you haven’t bought a bouncer or rocking chair for your first child already, then you probably need one for your second. This was a total life saver for me!

I could happily put my second baby in it for short periods of time while playing and giving attention to my oldest child.

16. Baby carrier

Having a baby carrier can also be a big help when you have two kids, in a similar way to the bouncer. You can wear your second baby in a wrap or carrier while you give some attention to your older one, particularly when playing outside.

I prefer a baby wrap for a newborn as it’s much more comfortable and safer for the little one, and then a carrier when they get a bit older.

17. Second humidifier

Humidifiers can really help your sick baby get sleep. And you might consider buying a second one for your new baby. Because when it’s winter, let me tell you, the chances of both your kids getting a cold at the same time and needing the humidifier in each room are pretty high.

Things to Check

18. Nursery Decorations

Is the second baby going to sleep in the same room as your first or in a separate room? Are they the same gender? 

Goes without saying that if your second baby is going to have a separate room, then you’ll probably want to get new decorations.

We had our second baby room share with us for a few months after she was born and then the plan was to move her into the same room as her sister. But that never happened: we were too scared they were going to wake each other up, so we settled with two rooms for now.

19. Bottles

If you bottle-fed your first baby and are planning on doing the same with your second one, you may need to check your bottles to make sure they’re still in good condition.

20. Diaper Backpack 

Of course you’ll need a diaper bag, but is the one from your first child still in good condition? Or is it big enough to now carry double the amount of stuff with two babies?

Investing in a diaper backpack allows you to be hands-free, which can be especially helpful if you’re juggling a newborn and a toddler.

Our first diaper backpack was falling apart after 2.5 years, so we bought a new one for our second baby.

21. Crib / Crib Mattress

If you’ve already transitioned to a toddler bed for your first child, then your second baby can easily use the same crib. However, make sure that the crib mattress is still in good condition and that you don’t need another one.

A crib mattress should be firm to properly support your baby and reduce the risk of sudden infant death syndrome. A used one may have lost some of that firmness or could have developed dips and bulges while in storage. 

Those are the top second baby registry essentials. What items did you find especially helpful when transitioning from one kid to two?
