Does anyone have any recommendations for nappies that fit tall, slim babies? DS is 10 months and 9kg and his little skinny legs have never had so much as a hint of a thigh roll. We have tried quite a few brands including pampers but still quite often end up with leaks around the legs. I'm not sure if we just need to size down (he's in size 3 or 4 depending on brand) or if there is a particularly good brand for little skinny bean babies.
