Hi everyone my 3 year old ds is constantly undoing the ties on his joggers. He is very tall so he's in a size up so they are loose around his waist they fit if I tie his ties together and knot them but he undoes them straight away! It's infuriating as his joggers keep falling down. I keep having to put him in jeans as they have the button bit inside to tighten them around his waist but when we go to soft play/nursery it's better he wear his joggers but he's obsessed with undoing them. He doesn't have many words yet so I cant even ask him why he's doing it. Ive not tied them tight or anything just enough that they don't fall down. Any advice of what to do from mum's who have also gone through this. I've triple knotted them and he's still been able to undo them. Tia. X
