Sitting upright is a skill you take completely for granted-but it's a fascinating feat for your infant! Your baby won't be able to master sitting unassisted until your little one has sufficient neck control to hold that little head upright. Expect this to happen around your baby's fourth month, when rapidly developing neck muscles make it suddenly simple to manage that once seemingly heavy head. Once your baby has mastered this head-raising skill, your infant will begin to do the classic "mini pushup." This cute pose involves your infant propping those arms on the ground and holding his or her chest off the floor at the same time. And by the time your little one is doing these gymnastics, it's only a matter of time until your infant can rest in a full-on sitting position. In the next several months, your baby will master this so well that you can expect your little one to pull into a full sit and to hold it unaided for minutes at a time. Once your infant IS upright, expect your baby to fall in love with seeing the world from this vantage point, as there is SO much more to see and learn from this new perspective! To help your baby learn to sit like a pro, make sure you give your little one plenty of playtime on that tummy. From this tummy-down position, your infant will WANT to lift her head and push up on those arms. Encourage this step by playing with your infant on the floor, using bright toys or pleasant noises to make your little one lift her head. As your baby masters this skill, teach your infant about sitting by propping your little one upright, legs in a wide "V" and arms together between them. As your baby becomes more and more comfortable with this changing perspective, challenge your infant even further by putting interesting objects JUST out of reach. The bend and stretch required will improve strength and small motor skills. Even more importantly, this movement is a precursor to new milestones, like crawling, standing, and walking!
