Matilda hates having anything on her feet & will pull anything off she can. The other night I went in to check on her before going to sleep & she was naked on her bed asleep. Thats right 10 degrees outside, and even the nappy was off. I had to redress her and tuck her in and hope for the best. I can't even have a heater in her room because she loves to play with them when she wakes up.
