So.. I think she is a week or two from crawling (she can lurch forward and almost has it), now and will be 5 months on the 29th. Some things worry me, though. We went to this event the other day and there were about 50 babies there. She just sat there, occasionally showed interest in the book we brought for her, but mostly just studied everyone. I wanted to introduce her to other babies but she wouldn't interact at all. All the babies who could sit or crawl played the entire time alone or with each other and all the babies who couldn't do much or looked like they were 3-5 months old just sat there and didn't show much interest in anything. They did this game where we moved her arms up and down and danced with her a little and she got really excited during it and while watching the girl leading it all, though.
The other thing is - she won't mimic me. She has never copied me. All my books say they start to copy you very early on. She does smile at me when I smile at her, but she smiles when she sees us, even if we are not looking. She is also squealing a lot lately and has ah-bo, oo-la type of words, but no dada or mama, yet. All the books I have say babies take great interest in their hands, but I've never seen her look at them... until last night. She was extremely tired, lying in the bed after nursing and really out-of-it / staring and she lifted up one hand to the light and slowly turned it back and forth and moved her fingers very slowly in different positions and studied it. It was really, really weird.
