Tummy time??

Dej • mommy to Aurora 👶🏽 Ftm 😀 happily taken

So my daughter who will be 4 months on the 2nd. HATES TUMMY TIME we never get the full 30 mins a day we need, she cries so much. But she loves sitting in her booster and can hold her head up and move it without falling everywhere.. I’m just super worried bc she’s like so fat(dr said she’s on the chunky side for her height) and when she does tummy time she just lies flat and breathes hard like it hurts 😭😭😭 what do I do to make it better for her 😭
