When my DD was between 1-6 months I got a lot of her clothes from H&M I remember they always seemed to be on the bigger size so for example if she was in 3-6 months in another shop, she’d be in the size below in H&M. She’ll be in 9-12 months soon so I have been looking for cute winter bits, I found some cute knitted jumpers in H&M but debating if I should get 6-9 months as that would be a size behind or go for 9-12, I did go in store yesterday and the 9-12 looked huge, I just don’t want to waste £80+ if the time comes in a few months and they don’t fit her
