Newborn to 1 month
Your newborn's hands remain tightly clenched during her first month. But pry open her tiny fist with your finger and you'll be surprised by her mighty grip. This is just a reflex -- your baby won't be able to deliberately hold objects for a while. And though they fascinate her, she hasn't yet discovered that her hands are a part of her body. At around 6 weeks she'll grasp one hand with the other and try to pry it open herself.
