Hi - I've bought a pack of long sleeve bodies from H&M for 12-18m and the only difference to the 9-12m ones I have from Mothercare is that they are longer - the width of the body is the same the whole way down.
Not sure if this is because H&M bodies come up skinny/long compared to Mothercare, or whether this is isn't an issue and that maybe babies grow more lengthwise after 12 months but not much widthwise?
I know it's a bit unimportant, but I can't afford to waste the cash, so if people generally think that H&M sizing is small, I'll take them back and get 18-24m instead.
Thanks
