That quiet, sleepy newborn is now a thing of the past. More and more active each day, your baby can’t wait to interact with the world around them. The physical evolution is astounding: when turned on their stomach, the four-month-old can already keep their chest and head up for about ten seconds. Stimulate them, cheering on their accomplishment and placing more toys around them.

Sitting up without help, in the stroller, is another developmental milestone. You’ll notice, in fact, that they won’t want to spend a lot of time laying in the stroller – with so much to see and discover, how could they not look around?

When they’re awake – which they will be more and more as time goes by – the child will complain if they stay inside the crib or even in your arms for too long. The baby wants the parents to talk and play with them and show them new things. Whenever you leave the child alone for too long, get ready to hear some “protesting”.

Some children, during this stage, tend to cry before going to bed. It’s a form of alleviating tension and to make the transition from awakedness to sleep. Others tend to breastfeed less during this phase – now that the stomach is a little bit bigger, they’ll be satisfied longer. While some doctors recommend introducing solid foods during this phase, it might be worth waiting a little longer – within possibility and according to your reality, of course! – to wean the child from breastfeeding. The WHO (World Health Organization) prescribes maternal milk as the only form of nutrition up until at least six months of age.

Your child’s appearance has also been going through some changes: their hair probably has begun to change, both in color and texture, and the color of their eyes has also changed. The definitive hair color, however, will only be defined at six months.
