Gross Motor
- Pulling to Stand - Your baby grabs onto furniture and pulls themselves up from sitting to standing.
- Cruising Along Furniture - Your baby walks sideways while holding onto furniture for support.
- First Steps (Emerging) - Your baby may take a few wobbly steps on their own, or they may not be there yet - both are normal at 12 months.
Fine Motor
- Refined Pincer Grasp - Your baby neatly picks up small items like cereal or peas between their thumb and pointer finger.
- Putting Things In and Out of Containers - Your baby drops objects into a cup, bowl, or box and then dumps them out again.
- Pointing with Index Finger - Your baby extends their pointer finger to touch things, poke at small objects, or point at things they want or find interesting.
Language
- First Words - Your baby says one or two real words like "mama," "dada," or "uh-oh," and uses them to mean something specific.
- Using Gestures to Communicate - Your baby waves bye-bye, shakes their head for "no," reaches up to be picked up, or points at things they want.
- Understands Simple Requests - Your baby understands simple phrases like "give me the ball" or "where is your cup?" especially with gestures.
Social & Emotional
- Waving Bye-Bye - Your baby waves when someone says "bye-bye" or when they see someone leaving.
- Showing or Giving You Things - Your baby holds up a toy or object to show it to you, or hands you things.
- Separation Anxiety - Your baby may cry or become upset when you leave the room or when they are left with a less familiar caregiver.
Cognitive
- Simple Problem-Solving - Your baby figures out simple problems, like pulling a blanket to get a toy that is on top of it, or moving an obstacle out of the way.
- Exploring Objects in Different Ways - Your baby tries different things with objects - shaking, banging, throwing, dropping, and poking at them.
- Imitating Simple Actions - Your baby copies things they see you do, like clapping, stirring with a spoon, or talking on a phone.
