Haha it's funny how different babies are, ruby absolutely hates being on her tummy, she just rolls straight back onto her back if put down on her tummy. I don't think she will crawl, she'll wait to walk haha
Does Rivkah have a jumperoo? It is the best thing we've bought Ruby, she absolutely loves it, I can highly recommend getting one if you haven't already. She's got a walker which she thinks is ok but she can't get enough of bouncing in her jumperoo
