What size clothing is your 6 month old wearing?
My DD has just gone 6 months and our size 0's are starting to get stretched a bit tight. She's very long (can't remember exact cm, but we hear "wow - she's so tall/long/big" ALL the time!). She's not "big", she's very lean, but just so long. She was born at 52cm and for memory at her 4 month check up was already 77cm or something.
We moved into 0's about 2 months ago, had a cold snap hit which saw me run out and buy up on warmer 0's clothing and I sat back thinking it would last me through winter. I'm now starting to look for 1's because the 0's are stretching tight - ie not sitting nice and baggy/comfy. When she decided to eat her feet today, the material gaped in between all the snaps - like when you try to get into a shirt a bit small and the material strains around your boobs (or in my case, your middle!)
I do prefer her in all-in-one jumpsuits, and I have noticed they seem to sit more "snug" than tops and pants sets, so that could be part of it? She's also cloth bummed in bubblebubs which aren't the trimmest of nappies, so I take that into account. But when I see the sizing charts in the stores saying Size 0 = 12 months, I start to wonder.
What size is your 6 month (or around) in? Is size 0 moving into size 1 at this age normal? common? super I have a basketball player on my hands rare?
