Tummy Time

We are having a hard time with tummy time. She has started to roll over when we try to do tummy time. And if we are able to get her to stay on her tummy it’s only for a few minutes. She can lift her head and will keep it held up for almost the entire time she is doing tummy time. But does not enjoy it at all. We have tried a bunch of different toys, boppy pillow and more. Any tips on how we can get her to do tummy time for long so she can strength her arms and neck muscles in order to crawl soon?
