Tummy Time Tips?

Madison
Hello ladies! I'm needing some help. My little one absolutely hates tummy time and i dont know what to do. I've talked to his ped about it, ans she recommended an exersize ball to roll him back and forth on, only issue with that is that hubby and I are tight on money. Being a first time mom, I don't know many tricks or anything - so thats why I'm coming yo you guys to ask if you guys know of any ways to make tummy time easier and more fun. Thanks in advance. 💕
