4 month old diaper size?

What size did/does your 4 month old wear? My 4 month old wears size 3. We switched to size 3 when he was a few days before 4 months old. He's 15lbs.

Edit :
I asked this because my friends 10 month old DS JUST switched to size 3 and she said my babys not normal  

2. shes still 12lbs.

I think DD was into 2s by then. She is 9 months now and in 3s. Can wear 4s but they are a little big

2. He's still in 2's at 7 months

yep, my son's 4mo (5mo on 10/21) and he's been in 3's for a while. He started getting red around the diaper area from them being too tight. So around 3.5mo we switched. Already thinking he needs to be in a 4 lol. He's 16lbs btw  

My son still fits size 1 he just turned 6 months old weighs 13 lbs 10 oz

He was in 2s

My friends 10 month old boy JUST switched to size 3 a few days ago. She said my babys not normal.

DD was in a size 2 at four months old, but I move her into size 3 last month (she is now six months old).

size 1. and i doubt she will be going to size 2 anytime soon. she is 10 lbs 13 oz

I believe Benji was in a 2 at that point.

Dd has been in a size 2 since around 4 months.. She's 12 months now and still fits nicely in a 2 haha she's long and skinny

1s but she could switch up to 2 anyday now just finishing the pack. She was 12 lbs 3 oz at her 4 month appt a few days ago.

LOL! I feel the same!!

2. She could have still fit in one, but we weren't sure for how much longer. She was only 10lbs 9oz.
