I have a Mommy Question ? My daughter is 4 months old and almost 5 months old she will be and i put her on tummy time when she was 3 months old and she looks like she is to stiff but she moves her hands and feet and legs just fine but when i put her on tummy time she doesn't want to do anything but screams when she gives up ? the reason im asking this yes i had a hard time with my son but he got the hang of it am i doing something wrong ? or do u think she needs therapy?
