My 7 month old has just learnt to crawl this weekend just gone and since then he fights having his nappy changed, as soon as we put him down on the change mat he starting trying to turn over and grips the top of the mat and sits up. I’ve tried giving him a toy to hold whilst I change him but just doesn’t work, it’s a nightmare cos when he poops it’s hard work trying not to get it everywhere. I really don’t know why he’s started doing this. Eek anyone else’s little ones do this?
