Between seven and ten months most babies start to move on their own, but the style varies. Some crawl on the belly, some shuffle on the bottom, and some skip crawling and go straight to pulling up. The American Academy of Pediatrics (AAP) treats crawling as a range, not a deadline, and notes the pincer grasp appears now, the thumb and forefinger meeting to pick up a pea or a crumb. That precision is why every small object on the floor is both a target and a choking risk.

Until about six months your baby lives in the present: what leaves his sight almost leaves his world. Around month seven something begins that psychologists call object permanence, the understanding that a thing still exists when it is not visible. Developmental logic ties this new ability to the peak of separation anxiety, because realizing you exist outside the room also opens a new door: that you, too, can disappear. The World Health Organization (WHO) lists searching for a hidden toy as an expected behavior at this age.

In month seven the fingers start working with the mouth, and your baby can pick up a small piece of food and steer it to his lips. The American Academy of Pediatrics (AAP) recommends moving gradually from smooth puree to texture with soft lumps, because delaying texture makes solid food harder to accept later. The right foods now are soft and dissolve in the mouth, cut into strips the size of your finger rather than into circles, because the round shape is the most dangerous for the airway. Four to six new foods a week is plenty.

Separation anxiety typically peaks between seven and twelve months, and it shows up in sleep first, because your baby wakes at night to check that you are still there. This is a normal developmental stage, not bad behavior, and it can add a few extra night wakings each week. The American Academy of Pediatrics (AAP) advises keeping the bedtime routine steady no matter how loud the crying, because changing the rules night after night resets his expectations to zero. Calm presence lowers his stress, it does not spoil him.

The I-want-you cry has a signature. It starts low, climbs the moment he hears your steps, and sometimes stops the instant you enter the room. That controlling tone is a sign his brain now pairs voices with specific people, a skill that sharpens in the second half of the first year. Pediatricians stress that this cry is aimed at a person, not at pain, and that answering it does not create a spoiled child. Red flags look different: a high-pitched cry that holding does not settle, or one with fever or refused feeds.

Once solid food starts and crawling puts hands on germy floors, diarrhea and vomiting become more common at this age. Losing fluids is not the usual danger; dehydration is the real risk to watch. The World Health Organization (WHO) advises continuing breastfeeds, formula, and fluids, and not stopping food unless a doctor says so. Watch for dehydration signs: fewer wet nappies, a dry mouth, crying without tears, low energy, and a sunken soft spot. A vomiting baby who cannot keep any fluid down needs same-day medical review.

This month combines new movement with a new mouth, so babyproofing stops being optional. Get onto the floor and hunt for everything that fits in a mouth, pad the table edges, lock the drawers, cover the sockets, and buy a bin he cannot open. Check that the fire extinguisher works and the smoke alarm is placed properly. Keep the vaccination schedule with your pediatrician, and save the emergency number and the poison control line in your phone.
