Anyone got any ideas? Poor DS is constantly either in too-short trousers which fit his middle or ones which are the right length but he has to constantly hitch up. Half the time I find drawstrings are just cosmetic and jeans just slip down his hips (the swine). He's a typical 6yo boy so super active and it's annoying for him to have to worry about losing his trousers all the time! Anyone else managed to crack this one?
