Microcephaly

Microcephaly is when a baby's head is small compared to the rest of their body. This happens because their brain hasn't grown properly. This can happen when a baby is still in its mommy's tummy or after they are born. It can be caused by different things, like infections or problems with their genes.

When a baby has microcephaly, it can cause them to have problems with their brain and development. They might have trouble talking, walking, and learning new things. They might also have seizures or other health problems.

Doctors can check if a baby has microcephaly by measuring the size of their head. If they find out a baby has it, they will need special care and attention to help them grow and develop as much as possible.
