Baby Essentials Series: 8 Must-Haves for Babies 0-3 Months

0-3 month baby essentials

You know that baby registry checklist they hand you when you walk into BuyBuyBaby? The one that made you burst into tears? Or was that just us? Suffice it to say, it’s unnecessarily long and intimidating. So much stuff!

We’re all about making new motherhood less stressful, not more. And one of the things that our MyNestwell expecting mamas feel the most stressed about is making their baby registry. So to help, we partnered with baby planning concierge Abby Kalter of Prepping for Peanut for a four-part series (0-3 months, 3-6 months, 6-9 months, 9-12 months) that takes a more minimal, and refreshing!, approach to your baby registry.

In fact, research suggests that clutter only adds to anxiety so eliminating an oversupply of “stuff” will surely make those newborn days a little easier.

Abby’s number one tip is to rethink getting all baby items all at once. Instead she says, “Think about acquiring items in baby phases. This will allow you to get to know your baby and your own preferences to make more informed decisions.”

So using Abby’s tip, we’re kicking off with what baby needs in those first 3 months. Here are the top 8 baby essentials, according to Abby, to put on your registry.

0-3 month Baby Sleep Essentials

The American Academy of Pediatrics (AAP) recommends that baby sleeps in their parent’s room for 6-12 months. If you’re breastfeeding, this is also most convenient. That’s why, this section doesn’t include a crib or full set of nursery furniture. You may still choose to set up your nursery ahead of time, but it won’t become an essential until you move baby to their own room.

There are lots of options for bassinets (high tech and super basic), but since babies outgrow them so quickly (around 3 months), I like to recommend something with a bit more longevity like a travel crib with a bassinet topper or conversion kit. A soft, easy-to-wrap swaddle and sound machine are musts for better sleep.

0-3 month baby GEAR ESSENTIALS

In the first three months, you’ll want to have safe places to put baby while you’re at home. There are LOTS of solutions for putting baby down: loungers, bouncers, moses baskets, etc, but many families are thrilled to have a baby-wearing carrier in the mix for especially fussy days. Besides being major space savers, they have an extended use, with some even being safe for wearing baby up to 35lbs! 

 You’ll also want a safe place to put them when you’re out and about. Now shopping for strollers is like shopping for cars; it’s highly personal and there are tons of lifestyle factors to consider. I recommend getting a personalized recommendation for stroller and carseat to get the best option for you, but here is one of my favorites.

Whether you are exclusively breastfeeding, exclusively formula feeding, or doing a little of everything it’s likely that you will introduce a bottle within the first three months. Some babies are picky and others aren’t, so I like to recommend a bottle box to sample a few brands before selecting your go-to. Often, it’s less about the bottle and more about who is offering and when, but having multiple failed bottle systems will very quickly add to clutter in your kitchen.

Newborns don’t need all that much when it comes to clothing. In fact, they can pretty much live in footed pajamas for those early months. There are lots of great options out there. Look for fabrics with slight stretch, zippers (snaps are no fun at 2AM!) and fold over hands to replace the need for mittens.

Now About Those Diapers…

It’s the little things that can really make a difference in those early days of parenthood. A wipeable changing pad will save you lots of laundry. With newborns using ~8 diapers per day, you sure will be doing a lot of diaper changes, so the easier clean up, the better. This is one I always recommend.
