I think it is when I'm approaching lol. I think some times he is a bit heavy footed around her, he doesn't realise that he is much bigger than her, so I'm just keeping an eye out to make sure he isn't squishing her too much! She seems happier since I put the sheet down as well, we just had a towel before and her legs were all over the place when she went on the wooden floor, now she looks much more confident and binkying. I also have to remember she has only been here since Saturday afternoon!
