Week 17. - What is my baby development at 17 week ?

While lying on my back I might start to roll on to my sides. The most important thing is that I do it in both directions.
I’m perfecting my eyesight focusing it on items further away.
I consciously try to reach my toys. If I hit them with my fists, it’s intentional.
My rhythm of sleep and wakefulness is stabilizing. I can already sleep for around 4 hours at night in one go.
I am able to recognize your voice and I’m slowly starting to react to sounds.
