Hi,
Don't worry too much about tummy time. Mine didn't like it either, but now all she does is commando style crawling on her belly all around the house. They all do things in their own time and we can only encourage them along the way. She is still very young, I would just put Alice on her tummy for about a minute at a time and then take her up. Putting her on my tummy didn't work for us, she still didn't like, so we did short bursts a few times a day.
