From ages 1 to 4 months, your baby will continue growing at about the same rate they set during their first few weeks. Here's what you can expect during these months.
Getting bigger
In general, babies gain between 1.5 and 2 pounds (0.7 to 0.9 kg) and grow 1 to 1.5 inches (2.5 to 4 cm) each month during this period. Their head size will increase in circumference by about a half inch (1.25 cm) each month.
These figures are only averages, however. You can keep track of your child's development as it compares to average
growth charts.
Head size & soft spots
At 2 months old, the soft spots (fontanels) on your baby's head should still be open and flat. But by 3 months, the one at the back should be closed.
Also, their head is more likely to be proportionately larger as compared to their body because it grows faster. This is normal; their body will soon catch up.
Looking longer & leaner: losing their "baby fat"
At 2 months, your baby will look round and chubby. As they start using their arms and legs more actively, though, muscles will develop. Their bones also will grow rapidly.
As their arms and legs loosen up, their body and limbs will seem to stretch out, making them appear taller and leaner.
Remember
If you have any questions about your baby's growth and what they look like at this age, talk with their pediatrician.
