I am starting to get concerned about my Lo. I noticed today that when I had a plushy rattle toy touching my LO's cheek, she didn't turn towards it. She just kept staring off into outer space. And she doesn't look at me at all, no matter how much I talk to her and play with her. I know that all kids reach milestones at different rates but I am starting to wonder because everyone tells me that she doesn't attempt to focus on them when they are holding and talking to her. should I be concerned or am I just expecting too much?
