When your baby is first born, her neck is far too weak to support her head, but it will quickly get stronger. By 2 months, you may notice your baby briefly popping her head up during tummy time, even if only for a few wobbly seconds. (If she detests tummy time at first, keep at it; it's an important way to build neck muscles and upper-body strength.) While your baby's head control will steadily improve over the next few months, you'll still need to hold her head when you cradle, feed, and play with her. But by 4 months, most babies won't need as much head support. At this point, she'll likely be able to raise her head even while lying on her back and prop herself up on her elbows (like a mini cobra) during tummy time.
