Mumsnetters- can you help? I have a very skinny two year old and all the trousers I buy for him fall down. The only style that works is like the parsnip pants that Frugi makes with the fold over waistband, and even those only work in smaller sizes than his actual age. They are a bit thin, and I was wondering if anyone has any bright ideas for thicker, warmer styles for winter that don’t fall down. We do dungarees all the time, but he likes trousers…
