Baby week by week · 9–12 months · 10–11 months: problem solving

Your baby at 42 weeks

From Brittany Ryan, Founder and Mom of Two

What’s happening at about 9 months

Your baby may experiment with containers, hidden objects and different ways to reach a goal. Cruising or pulling to stand may happen, but walking is not required at this age. Skills may appear briefly, disappear and return as practice continues.

What’s ahead

More controlled standing, releasing objects and simple imitation may develop. The next changes may be subtle before they become consistent.

A memory to keep this week

The first time they put something into a container

Safety first

Use close adult supervision for every activity. For sleep, follow current safe-sleep guidance and use a firm, flat approved surface. Keep small parts, cords, button batteries and magnets out of reach.

In the app this week

Try this together: In-and-out play, plus this week's memory prompts, a private journal and your Journey, quick logs for firsts like anticipated a routine and stood for a moment. One simple idea at a time, never 47.

Brittany Ryan

Founder and Mom of Two

Brittany is a mom of two with a background in early childhood development. Little by Little Together began with a beautiful, blank baby book. Like so many parents, she bought baby books with every intention of filling them; instead, they sat in a closet while life kept moving. So she built a personal assistant for parenthood that tells you what matters right now, offers one simple idea at a time, and keeps your story safe.

“You don’t have to remember everything at once. Little by little, there is a story worth keeping.”
