A baby’s weight usually doubles by the fourth month — and becomes three times the birth weight by the end of the first year.
Babies are about 70 centimeters long when they reach 12 months.
The head size increases quickly due to the brain’s fast growth which pushes the skull bones to expand.
This growth rate is only a guide. If parents are unusually large or small, the baby may follow their growth pattern — and if the baby was smaller at birth for any reason, growth may remain smaller or show spurts.
Call your doctor if your baby does not gain or loses weight over a period of days. Do this even if the baby presents no other unusual signs.
Babies progress slowly to gain control over their movements.
The neck muscles become progressively stronger, and your baby will have full control over neck and head motions by about 6 months.
The body muscles become stronger and can control many movements.
Arms and Legs
Movements become stronger and more purposeful.
In the first 12 months, there is a fascinating progression from the reflex grasping of the newborn to a precise reaching out and grasping things as tiny as bread crumbs between the thumb and forefinger.
Caution: Baby walkers do not speed up baby’s development, and may even slow it down. Baby walkers are very dangerous because they can cause injuries. It is illegal to sell baby walkers in Canada.
Babies have an urge to make sounds, just as they have an interest in the sounds parents or others make.
Your baby understands the tone of voice, too, and will frown if your voice is louder or not as loving. Before 9 months, babies understand when parents call their name, but if they hear ‘no’ they are not pleased. By 12 months, your baby understands several names of people or objects and shows that understanding by looking at the person or object.
Consult a physician: If your baby does not show interest, does not turn the head to sounds and if the baby’s own sounds do not get more mature.
In the first three months, an infant learns that there is a world of things and another of people.
Important Milestones: Observe that baby is alert, smiles, looks at and plays with you – and shows some distress when you leave (and also may ‘make strange’ when meeting new people).
Babies are curious to see, hear and touch. As months go by, their eyes follow people who move around. They learn to scan sounds — at the beginning with eye movements, later by turning their head.
As soon as they can grasp, they get hold of everything that is near, look at what they hold, put it in their mouth, shake it, bang it, throw it and pass it from one hand to another. If a toy they like is hidden, they remember and search for it under the blanket.
They bang two toys together and try to fit one toy inside the other.
