Help!! Need tummy time advice.

Cassie

My 2 month daughter HATES tummy time. As soon as I put her down she starts crying 😩 I’ve been propping her on the boppy and she still hates it. My son was never like this so I have no idea what to do. Her pediatrician said to let her cry while she does it because she has to get used to being on her belly but it breaks my heart a little every time. You ladies have any advice?
