Need some advice on how to keep my DS's feet warm, while he learns to walk in this cold weather. I have some cruiser shoes from mothercare, but this weather is just too cold for a thin pair of socks and his cruisers. Still, all the boots I see are big and would be rather difficult for him to manoeuvre in I feel. Any suggestions on what brands to look at? I'd buy some really warm socks if I knew where to look, but can't seem to find those anywhere either. Help!
