Most babies will sit with support at this stage and they’ll enjoy standing upright with support as well,    more exciting is that your baby will be able to roll. This movement is important because it’s the beginning of the skills of locomotion that move baby from one place to another. 

Your baby might enjoy a little independent playtime. If you leave him on his back, he might grab his feet or fingers and stick them in his mouth. If there’s a toy, he’ll shake it and taste it.

Another important fact is that, at this age, your baby’s vision will also improve.

Because of this, sometimes is difficult to feed a 4-month-old:  because he’s looking all around the room. But, don’t worry, because DANALAC stage 1 provides him with all the nutrients that he needs to grow happy and healthy.
