Feeling discouraged

My LO is 9 weeks and we are having the hardest time with tummy time. She absolutely hates it and screams her head off whenever I try. I have successfully put her down for short naps on her belly (while I’m watching) but will not entertain being on her belly while awake. I just read that she should be holding herself up on her forearms by now but we aren’t even close. What do you do to help make tummy time less of a chore and more fun for your LO. I don’t want her to fall behind in progression!
