Amber
My daughter was born march 22nd 2016 and its been rather well up untill today. I cant stop crying because she no longer wants to cuddle with mommy she wants to nap alone. Is this post partum symptoms. Also she doesnt like tummy time. She doesnt push up she still tries to "fly" and all she does is scream cry. Now she however does want to stand and take steps. Is this normal hlw can i get her to tolerate tummy time n less standing? I need help!!! It all makes me cry uncontrollably all the time. TIA
