Ds (almost 3.5) is starting school nursery in September and I'm struggling with ideas for trousers . Uniform states black or grey trousers and no complicated zips / buttons for early years . I think soft joggers would be best as don't want him in proper uniform trousers yet but find they always tend to have baggy waistbands that slip down as he's quite slim and they always have a string to tighten which he obviously can't tie/ untie himself for going to the toilet . At the moment he lives in adjustable waistband shorts/ jeans and if he's had joggers on I'm there to help him adjust them for him . Any recommendations ???
