DS2 is titchy - he's almost 3 and in 12-18 month trousers. He's very skinny and now that he's no longer in nappies trousers are basically falling off him. I have him in leggings at the moment, but I'd prefer him in something warmer soon as we're in the north west and he spends most of his time outdoors. Any recommendations for brands for joggers? So far I've discovered that m&s is a definite no, I think I could fit two of him in them!
