Tummy time tips

Anybody have any helpful tummy time tips?! 
I probably should have done more with her when she was first born, she is two months old now and I feel like she should be doing a bit better on her tummy. She has had such good head control when you hold her that I figured I could kinda slack on the tummy time.
I'm trying to increase it but it's hard to find a good time while she is awake for such a short time and a good portion of that is feeding.
When I put her on her tummy now she barely moves her head from side to side (though she does great not on her tummy with that), and then she just hates it and it busy sucking her hands the whole time and doesn't seem to really be trying to push herself up.. :/
