What age did your baby outgrow size 1 LL's?

Max has started outgrowing his size 1 bamboo little lambs and I am a bit gobsmacked as whilst he ha realy chunked out and is very long I didn't expect him to start outgrowing them at 13 weeks old. I tried one of ethans size 2 today and it fit better but I don't have many so woud need to replace the size 1's quite soon me thinks. What age did your baby outgrow the size 1's? (Why do kids have to grow so fast?

My reuben is still in size 1 bamboozle stretchies with the tabs touching in the middle and has only just increased the rise about a month ago. He is 6 months next week and nearly 14lbs. Not sure about little lambs tbh but they do have a sale on ATM (although only nippa fastening cottons in size 2)

Max is 14 lbs already at 13 weeks old lol. I will have a look on the website to see what deals they have going. Thanks

around 3 months ish he outgrew the rise.

9 months i think its the rise

My wee boy is the same, Angie. He's almost 11 weeks and 14lbs. I noticed last night the sze 1 LLs are getting too short in the rise.

I didn't have any sz1 LLs but Isabel is just about out of her sz1 bamboozles (old style nippa) and has been wearing sz2 LL for a week or so now. She is 13w and about 13lb. I need to go check out that sale

4 months and it was the rise x

dd out grew at 2.5m - she was a skinny little thing, but got builders bum in them.
