SMOOTH OPERATOR
He's no Fred Astaire yet, but your little one's movements are getting a bit more coordinated. You'll notice that the jerky arm and leg movements of his newborn days have given way to smoother, more circular motions, especially when he's watching people.

Give your baby enough space to stretch and move his arms and legs. Lay a blanket on the floor and let him move as he pleases. These movements can help your baby strengthen and tone his developing muscles. On his tummy, he'll start to push off with his legs — the first step in getting on the move.

SOUND SLEEP ADVICE
Whether you envision your little one sleeping independently in a crib at an early age or sharing a family bed in the coming years, a soothing and predictable bedtime routine will help your child nod off and get the rest he needs. And it's not too early to start.

Your routine can include rocking, singing, a bath, a bedtime story, cuddling with a transitional object (such as a soft blanket or stuffed animal), being carried around the house and saying goodnight to each room — whatever makes sense for your family. The ritual will evolve as your child gets older.

"HELLO, MY NAME IS?"
At this age, your baby should be open to making friends with babies and adults alike. You may notice that he smiles when he sees anyone come in the room or holds out his arms when someone wants to hold him.

Now's a good time to introduce your baby to sitters or other people who might be looking after him later on. Have potential caregivers come over and spend time with you and your baby. Later on, he may be consumed by stranger anxiety, making a simple introduction seem impossible.

Do remember that babies have different temperaments and some are less open to new people than others. If your baby doesn't welcome someone new with open arms, be patient, hold him close, and reintroduce him. It may just take some time. Familiar surroundings will help introductions go more smoothly
