20 weeks pregnant: what's happening

From Brittany Ryan, Founder and Mom of Two

You are halfway to 40 weeks, an exciting milestone. Your baby is swallowing, moving, and practicing skills that will be useful after birth. The little person you've been imagining is becoming more active and defined with each passing week

What's ahead

Movement may become stronger and more recognizable in the weeks ahead.

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.”
