Here's what's happening at this age - milestones, common concerns, nutrition, sleep, and vaccines.
Developmental Milestones
Based on the 9 Months checkpoint
Gross Motor
- Crawling - Your baby moves across the floor on hands and knees, or scoots on their bottom or belly. Any style of getting around counts.
- Sitting Without Support - Your baby can sit on their own without needing to prop themselves up with their hands or lean against something.
- Pulling to Stand (Emerging) - Your baby grabs onto furniture or your hands and pulls themselves up to a standing position.
Fine Motor
- Pincer Grasp (Emerging) - Your baby is starting to pick up small things using their thumb and pointer finger, like a small piece of cereal or a puff.
- Transferring Objects Between Hands - Your baby passes a toy or object from one hand to the other.
- Banging and Clapping Toys Together - Your baby bangs two objects together or claps toys against each other.
Language
- Babbling with Consonant Sounds - Your baby makes strings of sounds using consonants and vowels together, like "bababa," "mamama," or "dadada."
- Responds to Own Name - Your baby looks at you or reacts when you say their name.
- Understands "No" - Your baby pauses or reacts when you say "no," even if they do not always obey.
Social & Emotional
- Stranger Anxiety - Your baby may become clingy, fussy, or cry when unfamiliar people approach or try to hold them.
- Looks Where You Point - When you point at something, your baby follows your finger and looks at what you are pointing to.
- Enjoys Interactive Games - Your baby enjoys back-and-forth games like peekaboo, pat-a-cake, or being gently bounced.
Cognitive
- Object Permanence - Your baby knows that something still exists even when they cannot see it, and will look for hidden toys.
- Exploring Cause and Effect - Your baby does things on purpose to see what happens, like dropping food off the highchair or pressing buttons on a toy.
Red Flags to Watch For
- !Does not bear weight on legs when held in standing position
- !Does not sit with help or support
- !Does not babble - no "mama," "baba," "dada" sounds
