3 Month old must haves for baby

When shopping for your 3 month old baby it is sometimes hard to determine what you really need. I am a no frills mom who like to just by the bare essentials because they are always growing so fast. 

That is why I am sharing the no frills 3 month old must haves for your baby to help you save money on baby items. If you want to save even more money when raising a baby you will want to check out our awesome post on how to save big on buy baby items used. 

3 year old must haves: clothes

Here are my 3 year old must haves favorites when it comes to clothes. 

2 Pack of White Onesies. I love Carters for these. I know a lot of people put these under their clothes… We just wore them as shirts with cute pants/shorts. Be sure to grab two packs so you have extras for those blowouts and you aren’t constantly having to do laundry. 

5-6 Sleepers I am a huge fan of these ones!

1-2 Packs of Onesie shirts He had about 5-8 shirts he would rotate through. We always had plenty.

Another item on the 3 month old must haves are these cute pants! 5-7 Pairs of Shorts/ Pants  is the perfect amount. TJ was born at the end of June in Texas… I will be honest he wore shorts twice in the first three months. Most of the time he just rocked a onesie because it was hot. The other times he wore these soft pants from Carters! In fact, he still wears these!

Feeding and Diapers

TJ was exclusively breastfed, so I didn’t have a need for bottles and such, but I did get a few from the hospital while we were there that I would use on occasion. 

I made about 8 burp rags which seemed to be enough. We never ran out.

When I pumped I used a pump I rented from the hospital, but it was similar to this one (Although nothing compares to those hospital pumps… I was able to rent it for $75.00 a month) to freeze breastmilk and I would use Lansinoh Storage Bags For breastfeeding storage tips be sure to check these out!

Diapers and wipes are are a must on your 3 month old must haves. I stocked up on all my Huggies Wipes at Costco when they have them on a rebate to save money on wipes and then I usually bought Huggies Diapers. I love using Amazon Subscribe and save to have these items shipped right to my house on demand. 


With a summer baby, there is only one kind of blanket you need! The Muslin Swaddle Blankets! We had 10 of these because I had bought a couple and then two people gave them to us as gifts. That was way too many! 8 is plenty!

We had a crib sheet, a bassinet sheet, and a playpen sheet that we picked up at Target and that was it.

Baby Holder

For Talie we had a Baby Bjorn, which worked great, unfortunately, TJ was bigger and did not fit well in it. We chose to get an Ergo Front Pack. It has been an absolute lifesaver with him… He has lived in it!

Things to Do/ Places to Lay

Let’s be honest… Babies don’t do much in the first three months! They don’t require toys or much of anything else. 🙂

We had a playpen set up in the living room so that Talie would not squish him on the floor and it worked perfectly. Then, we were able to put the bassinet part in it so we didn’t have to bend over and pick him up!

We borrowed a bassinet from a friend for our room… I wouldn’t go out and buy one if you don’t have one! We used our playpen for Talie and it worked perfectly!

We also had the crib left over from Talie so we didn’t have to buy that again.

I had a
Boppy from Talie and never used it, but for TJ it was awesome because he had reflux. It worked miracles to prop him up so he wasn’t lying flat (and yes, it has a pink cover on it still).

The only other thing we swear by with places to lay down is a playmat… You will get your money out of it!

All of my kids have loved them and they last. The one I have is 7 years old and is in great condition. It is similar to this one.

Carseat and Stroller

When choosing a car seat and stroller I did splurge a bit when it came to these 3 month old baby must haves. This might have been where I was a little pickier and spent a little more money, but it has been so worth it!

Carseat: We loved Talie’s car seat and it was still in good condition so we are using it for TJ. It is the Chicco KeyFit30. We did have the matching stroller for Talie and were not impressed. It broke on a trip we took once so I wouldn’t recommend the stroller unless you really want it to match.

Strollers: With Talie still being little we needed a double stroller, but I also knew I would go places without her and didn’t want two strollers always in the car.

So, after searching high and low, I found the stroller of my dreams…It works as a single and a double; in fact, you could also put a board on the back for another child to carry 3! You can also arrange the seats many different ways and buy an attachment for your car seat. This comes at a steep price, but I promise I have loved it so far and have not been disappointed. It is a City Select Double Stroller.

Jogging Stroller: I knew I wanted to start walking and eventually running right after TJ was born. I had a BOB Stroller before and loved it, so I knew I would be buying a Double BOB Stroller. This one gave me the biggest bang for my buck including the parent tray, which I wanted.

This is all we had with our minimalist last baby as our 3 month baby must haves. I can honestly say we did not miss the bells and whistles that we had with the other kids.

As he grew out of his clothes we weren’t sad about giving them away or donating them because we had not bought a lot or spent a lot knowing how quickly babies grow. All the rest of the items mentioned, he still uses.

What a difference having a minimalistic baby did for my peace of mind and my pocketbook!
