Follow these four steps to swaddle your baby safely:
Lay out a lightweight blanket— about 42 inches square—in a diamond shape. Fold the top corner down and lay your baby on it, her shoulders at the fold.
Sometime between 16 and 22 weeks, you'll start to feel your baby move.
Keep track of your baby's development each week. Personalize your calendar by entering (or calculating) your due date* below.
