My daughter is 9 months, almost 10.
She army crawls like a pro. She alternates arms and legs and is very fast.
She can get into a quadruped position and rock but will go back to her belly to move.
She can climb over obstacles like our legs and can sit up on her own now, but she often uses a cushion or nearby object to help her. She just learned to do that this week.
She’s stable when sitting but sometimes falls over when trying to get out of a sitting position.
She kind of attempts to pull to stand sometimes but can only get her butt slightly off the floor. She can stand holding onto something for awhile, but depending on the object she sometimes leans forward onto the object for support (e.g will do this with her walker or activity table but not the baby gate)
Didn’t know if this was something worth looking into early intervention for.
