Someone please help.. diaper changes

Ever since my daughter turned 7 months old she will not sit still for diaper changes and putting clothes on. She is now 11 months old and its only gotten worse. She screams like crazy, cries, arches her back and scrapes her head across the carpet. I’ve had to learn to change her diaper while shes on her stomach and find many positions to put clothes on her but enough is enough i cant handle it anymore. Giving her a toy doesnt help neither does talking singing clapping. Ive done the whole talking through the process with her even though she doesn’t understand but i just dont know what else to do it takes three people to change her diaper😭
