Your little one first discovered her hands a couple of weeks back, and now she's downright fascinated with them. Watch as she examines them, puts them in her mouth, and tries to suck on them. Don't worry if your baby becomes a bit obsessed with her newly discovered digits: This form of self-comfort can be very soothing for your baby — and can possibly give you a little break, too.
This week, when you go to pick up your baby, she may be able to lift her head and hold it up for several moments, or even longer, while lying on her back. When sitting with support, she should be able to hold her head steady and erect. When she's on her stomach, you might see her lifting her head and chest to about 45 degrees as if she were doing mini-pushups. You can offer encouragement by sitting in front of her and dangling a toy.
