My 9 month old is growing out of his shoes again and so I bought him some size 6 shoes for a family dinner and it seems they’re about maybe half a size too big (maybe even less!) but since they’re like boat shoes, so they don’t have velcro straps or laces and they come off a little whenever he takes a step. It’s not a big deal to him since he’s wobbly when he walks anyways but I wanted to know if there was something I could do to help them fit better. Any suggestions??
