Any tips on rolling from front to back?

Little man has mastered rolling from back to front, but not so much front to back. Due to his open heart surgery we couldn’t do tummy time for weeks and only recently got the all clear to start so he’s slightly behind in terms of rolling from front to back. We’re trying to implement tummy time as much as we can during the day without him getting pissed off or fed up but does anyone have any tips or pointers to encourage it? Thank you! ❤️
