|By two weeks of age your baby will probably have regained most or all of the weight that he lost in his first week.
In the next few weeks you can expect your baby to look at your face, startle with loud noises, lift his head and begin to smile spontaneously. He may even begin to recognize familiar objects and sounds.
If using a pacifier, try and restrict its use to when your baby seems to need the self-comforting behavior of sucking. Avoid using it every time your baby cries (it is usually better to pick and hold your baby to comfort him when he is crying) and to be safe, use a one-piece commercial pacifier and do not hang it around your baby's neck.
Remember that all babies are unique and they have different temperaments. Many are quite and calm and have an easy temperament. Others have a difficult temperament and may be very active and or sensitive and get fussy easily (and may need more structured and less stimulating environments to stay calm). Or your baby may have a temperament that is described as being slow to warm up, being quite and shy and slow to adapt to new things and he may need to be slowly introduced to new things. Try and keep your babies temperament in mind as you react to her needs.
