Hello, we are new users here. I don't understand anything yet. I have a question. Please advise. My child is 3 months old. Not very confident but can hold their head up (there is back muscle tone otherwise it would be a banana pose). Touches and grabs toys hanging above, also touches toys with one hand then the other, can hold them in their hands. Smiles a lot, babbles. Always looks at faces, frowns, is happy, tries to squeal but hasn't succeeded yet. The only concern is that they don't really follow toys with their eyes when moved from side to side; they might look in one direction and then switch back to me. Also, I'm not sure if it's normal, but they don't really control their hand movements yet. Our child turned 3 months old on January 28th.
