She arches away from you when you try to sit her up. She goes straight as a board. She can't get herself into sitting, and once she's there, she can't get back down without toppling. And crawling? She's not even curious about it.
People will tell you she's just "a stiff baby" or "not a mover." That's a description, not an explanation.
A baby who can't fold in the middle can't get in and out of positions. And a baby who can't get in and out of positions doesn't practice — so she doesn't progress. That's the loop you're stuck in.
In this session, you'll watch me work with a 8-month-old who both arched instead of bending. You'll see how I get a stiff baby in and out of sitting, onto her knees, and back down to the floor — and what to do at home so she starts doing it herself.
