DS is 14 months but not walking yet, so I don't put shoes on him, and socks last precisely 0.05 seconds before being thoroughly explored, ripped off and lost, so I never bother with them on their own - his feet are warm enough in the footmuff anyway, and if I get him out of the pushchair anywhere it's usually heated.
But today at the Children's Centre I had about four people exclaim at his socklessness and one woman told me twice that he didn't have any socks on (in case I hadn't noticed?) and that he had cold feet (he didn't).
Admittedly it was colder than usual in there today since it has been closed over Christmas, but he didn't seem upset by having bare feet and they didn't even feel that cold to me. Why are people obsessed with socks?
