My daughter is 7 months old. She is our second child, so naturally she hasn’t had as much attention, nurturing or stimulation as her older sibling, though we’ve tried our best. But she has been very responsive when we try to talk/play with/read to/sing to her. Often she will not make eye contact at all. We literally have to bend over backwards to get her to smile or laugh. She really only seems to enjoy being thrown in the air. Also the only noise she ever makes (apart from crying) is a funny little growl.
Is this normal?
Did anyone else have a child like this who turned out to be fine? What were they like when they were older?
