Hello. I've had those before. When they are undone it looks as though your baby is wearing a wrap around vest. It's just fashion, I think. I don't feel that baby benefits any more than where the poppers typically are.
Hello mumsnetters, have you tried a bodysuit with poppers in the front that you can undo like all in one sleep suit. I just noticed them in mothercare, they are much more expensive then normal one, I just wondering why. Thanks
