After the baby's first month, most parents and babies are now developing a routine.  Your baby's growth will continue to be dramatic.  In general, babies gain between 1 1/2 and 2 pounds and grow 1 to 1/2 inches each month during this time frame.  Babies typically develop a chubby appearance and become more active and interactive.  The posterior fontanelle (the soft spot on the back of your baby's head) typically closes by 1 to 2 months of age.  The anterior fontanelle (the soft spot on the top of your baby's head) will remain open for several more months. Your baby will begin using her arms and legs more freely. She will have the ability to stretch out in therefore may look longer and thinner.

How much should my baby be moving?

Most babies won't be able to crawl or sit up until at least six months of age. Nonetheless, your baby should be holding her head up on her own and should be moving her arms and legs vigorously. A baby held in a standing position may be able to hold her own body weight for several seconds while supported. Many of your baby's reflexes will remain for several months.  If these include the fencing reflex, also known as the tonic neck reflex,  and the Moro reflex if, also known as the startle reflex.

What about head movement?

At one month of age, your baby should be able to hold up her own head briefly when held in an upright position.  Her neck strength will improve over the next few weeks. A baby that is placed on her belly will lift her head enough to look around and perhaps turn  her head to the other side. A baby lying on her back will not likely be able to lift her head from a flat position.

What about leg movement?

After one month of age, your baby's legs will be quite strong.  In fact, a baby held in a standing position will likely be able to hold her own weight for a few seconds when supported. It is important to know that although a baby at this age won't likely be able to roll over, she still may be able to push herself off of a table or bed by kicking or pushing off a wall.

What about arm movement?

Between one month and four months of age most of your baby's arm movements will continue to be random. Typically at 3 to 4 months of age your baby will begin to bring her hands to her mouth intentionally. Before this time, if your baby's hand reaches her mouth it is typically by accident and will often fall away after a few seconds. Your baby will likely begin reaching for objects at between 3 to 4 months of age.

The hands typically stay gripped tightly in the first month or two.  Objects placed in the hand may be held for several seconds or longer.  However, over the next few weeks, she will begin to open and close her hands voluntarily.
