6 week old just uninterested.

My LO doesn't want to do anything!!! She just lays there during tummy time, doesn't care to look at any lights or toys or anything!! She'll wiggle a bit when she hears me and she'll look at me when I'm talking to her( most of the time). I haven't even gotten a real smile!! I know every kid is different and not to compare her to others, but I'm getting worried. When did your LOs start being lively??

Picture just because she's precious.
