Prepare for regular medical checkups and address developmental milestones, including gross motor, fine motor, cognitive, language, and social-emotional skills. Expect significant changes in feeding habits, transitioning from breastfeeding or bottle-feeding to introducing solid foods. Establish healthy sleep patterns and routines, tackling common challenges like night wakings. Essential caregiving tasks, such as diapering, bathing, and play, foster infant growth and create a strong bond with parents.
