DS is nearly 13 months. He crawls everywhere at high speed and pulls himself up on things. When we go to the park with DD, she runs around all over the place and he follows her on his hands and knees. On climbing frames etc he now climbs up the steps and ladders (even big ones), tries to walk up the stairs, cruises his way along the walkways, etc etc. He has no shoes so sometimes wears socks, sometimes bare feet.
Anyway, I have heard other mothers (and my own mother) making comments about why he doesn't have any shoes on, poor child etc etc. However, decent ones seem so expensive and I'm not convinced that buying cheap ones will do more than socks to cover his feet.
