DD has just started crawling and realising that she is seperate from me. She loves to turn onto her front when I am trying to change her nappy and throws a wobbly if I try to turn her back over onto her back. Likewise when it comes to dressing her. It's a wrestling match and I can imagine it will only get worse. She loves the struggle and finds it funny, often crawling away as I try to deal with her. I have tried tickling her which sometimes works but how else can I make this easier?
