Baby clothing sizes So I had always assumed that clothes that are 3 months are the same size as…

Yes she's right! It goes:

Newborn, 0-3, 3, 3-6, 6, 6-9, 9, etc.

I am so thankful for the in-between sizes. It allows for seamless transitioning.

Interesting! Thanks for the info. I had no idea! I feel like most of my daughter's clothing are the 3, 6, and 9 month sizes. Looks like I'll need you invest in some 3-6 and 6-9.

We buy mostly carters, and they do 3,6,9,12 mo sizes. Kendall is now in their 6 month due to her length and weight.

No matter what size I always look at the tag to see what the brand recommends for height/weight and I buy based off mainly the height since my kiddos have daddy's long legs

And of course every brand fits different! Lol so confusing. Mine is almost outgrown the carters 6 months stuff but the some of the George or joe 3-6 months fits her.

Not only is every brand different, but even the same brand is different. I have 3 pairs of 3 month old carter pjs (they are the pant suits ones with the feet), they are all different sizes. One, the legs are 3 inches longer! I also have some other 3 month pajamas that are closer to 6 month old or 9 month old.

I'm kinda frustrated that all the sizes are different. I want to order her some more clothes online, but I feel like the sizing is all over the place. It would be fine if it's too big, but don't want it to be too small. I wish they would be consistent!!

I have no idea honestly I just stick Addison is anything that doesn't look overly huge on her lol

I've noticed some of the in between sizes are wider, but shorter in length. In the 0-3 month size my daughter is to tall for, but the width is still so baggy on her.
