Hello, my son is 10 months and he's a chunky baby. He's in 9-12 month clothes but the tshirts are a bit snug on his belly and it's impossible to find trousers/leggings that fit his thighs! Everything feels skin tight on the poor baby. He's in Next, H&M and M&S clothes which I thought were roomier. Any other brands that are good for baggier 9-12 month clothes? Or if I go up to 12-18 months, what shops come up small? Hoping to do a shop on Vinted for second hand bits.
Thanks!
