We had the baby down on the tiles a lot while we were on holiday, encouraging her to explore and make her way around, and work on her 'worming'. And to do weird stuff.
One afternoon as the husband was napping, she backed herself up to the ottoman and started rocking back and forth on her hands and knees (as she is want to do). Each time her butt hit the ottoman, the legs would squeak as they dragged across the tiles - "squeak... squeak... squeak...squeak...". Then there was a pause while she backed herself back up to it again, and off she went again. And again. And again.
Another afternoon (funnily enough, the husband was napping again!) I was trying to take a photo with the phone to post to the internet for my family, when she started behaving like a dog. She would put the strap of our backpack in to her mouth, pull backwards on her hands and knees, and shake her head. When the strap fell out, she would shake her head like 'no, that's wrong', and then put it back in her mouth and start shaking it again.
I showed the husband when he woke up, and he was perplexed as I was.
Until we were on the plane on the way home and he remembered he was playing that same headshaking game with her and the toggles on his hoody before we even left for holidays. Thanks for that one, honey!
