For the first three months, it would basically be sleeping and eating for your newborn. You, as a mother will have to take care of your baby while feeding, bathing, changing your baby’s clothes and diapers, putting your baby to sleep and definitely when your baby is crying.

Initially, for the first few weeks your baby would cry a lot, trying to adjust. You need not worry about it. Feeding your baby from regularly and providing your baby with the correct sleeping environments are necessary during this phase. Do not over feed your baby. When your baby does not want to eat any longer, it is understood that your baby is satisfied. The sleeping hours of newborns vary a lot. When your baby is tired, put your baby to sleep. Remember your baby is affected by the change of noise levels while sleeping.  While bathing your baby, be careful and always be present while your baby is taking a bath. Also make sure that you clean your baby while changing diapers. Babies have a tendency to have infections and rashes from diapers.
By the end of the 3rd month your baby will have become much more active and will start to grow.
