The baby is one hundred days old. If calculated based on this number of days, the baby is already over three months old. By the time they are over three months old, many babies can already lift their heads up. You should know that looking up is the first big movement that babies learn, but there are also some hundred day old babies who cannot look up. So, what if a hundred day old baby can't look up?
At 100 days old, it is important to pay attention to the size of the baby's head. Some babies have heads that are too big, which will definitely limit their ability to lift their heads, while others have relaxed muscles due to the fact that infants at 100 days old will definitely have an impact on their ability to lift their heads. If it is indeed muscle relaxation, this should be noted, otherwise it will affect the development of the baby's major movements in the future.
A hundred day old baby cannot look up, so it is important to take the baby for a check-up. If no abnormalities are found during the check-up, there is no need to worry. The baby may need some time, so parents need to be patient. Usually, it can also help babies learn to lift their heads and let them lie down as much as possible, which is helpful for exercising their neck.
In fact, some babies learn to look up between four to six months old, and parents can consciously train and guide them in their daily lives. For example, using some toys to make babies look up. You can also let your baby lie down more often, which can exercise their neck muscles and help them learn to lift their head.
