Week 9. - What is my baby development at 9 week ?

I start to lift my head at a 45 degree angle to the ground.
I’m unable to change my position on my own yet.
I can keep my eyes in one position. I focus most often when you lean to face me.
I react to loud noises, footsteps, and sounds from all around me.
My movements are not coordinated yet. However, I still enjoy waving my arms and legs.
