Im having trouble with vests and ordinary trousers sometimes. Some fit but Id like to know what would definately fit.. he is long for his age too. I just keep chucking clothes in the corner every night for more things that dont fit!
I think it get a bit easier once they get past 4 or 5 months. I put Kacie in 3-6 months bottoms from about 8 weeks old, most of her jeans have come from Asda. And I just stopped putting her in poppered vests at about 5 months. I put a plain long sleeve top under what she's wearing to give an extra layer or Matalan sell proper vests, non poppered, from 6-9 month size
Bella's wearing some 18-24 month soft trousers from Sainsbury's over her nappy and wrap today. They fit fine. TBH, we only ever buy her cheap-ish trousers from Sains/Tesco/Asda and have not really had any problems with them. But she does wear wool/fleece etc most of the time.
