DD will be three in May. She is a bit smaller than average and quite thin. I am finding it impossible to get trousers to fit her now that she is out of nappies as 2-3 years is too big for her but smaller seem to allow room for a nappy and are also too big on top althought a good fit on the leg. I tried Jojo Maman Bebe after a recommendation here and the ones I got are lovely but neither the 2-3 or 18-24 month fit her properly. She needs mostly cotton as she has eczema and skirts are out til the weather improves as tights make her itchy. Any suggestions? Does anyone know of brands that are small fitting?
