Belly to belly tummy time will have the same effect

Eventually she will like the tummy time on her own. I've had two preemies, both of which never did much tummy time aside from the time where we went belly to belly. They were sitting up at 4 and 5 months, crawling at 5 and 7 months, and walking at 10 and 13 months. they have good fine and gross motor skills. Just saying this so you can have some peace of mind. If the tummy time doesn't happen your baby girl will be alright, and the tummy to tummy time can help too. If that isnt working very well, try to do it more on an incline so babie's head is higher, sometimes even babies without reflux can be a little uncomfortable in a flat position, but more comfortable if their heads are more elevated.
(my children were born at 8 months instead of 9.5, I understand the need for development in children who were born even earlier then that, but I'm sure you can get that development with tummy to tummy time.)
Also on a side note, if having a preemie interfered with your ability to breastfeed (or even if you just plain ole didn't want to do it) you can try kanga roo care, which you can do during the tummy to tummy time. You may already be practicing it or have heard of it, but here's the benefits just in case.

Congrats on your little girl, she is beautiful!
