Tummy time

Lacey

One month old, everytime I do tummy time she can roll herself over and will asap. So I keep putting her on her tummy, we do this about 3-4 times before she gets mad and screams. Often I'll hold her over my shoulder and she'll. Lift her head and push her arms off my chest and can hold herself like that for awhile. Other than that she fights Tuy time like nadt. I don't want to make her scream but I don't want her to have a flat head either.
