K has always been lifting her neck, turning it side to side, and basically exhibiting a strong neck and desire for control since Day One! I looked up Tummy Time and some places say we should start newborns with some tummy time every day right away! But also,that it might irritate the umbilical cord stump? So what to do? She is only a week old, so is she ready or too young for tummy time? What did you do about the umbilical cord?
