Hi i have just bought a preloved HH which arrived today. I quite like it but the velcro is a bit shabby looking and it's not very snug round my LOs legs and bum area which terrifies me as he has sloppy poos. Do you think it's a case of needing a size down? I bought a medium for approx 15+lber (yes i need to get him weighed but they closed the clinic i was using
) or is this the norm for them?
