Is it normal for my 4 month old little girl to change at this age? She is crying/screaming more than usual and she has been sleeping through from 8 weeks. The past week has been awful, she won't sleep through and will stir all night.

She now has her two bottom teeth, they came through a couple of weeks ago. Could her top ones be moving around and causing her discomfort? I give her teething relief and it doesn't seem to help.

She'll play with her toys for 10 minutes and then start crying/screaming. Only when I pick her up, she's grunt at me a few times and then stop. Then she'll smile!

I'm so confused...is this just a 4 month thing?

I started solids last week but she loves them...opens her mouth wide and enjoys every mouthful, surely it couldn't be that, it seems to satisfy her afterward and she seems pretty happy for a while. I know what everyone says about starting solids early so I don't really want people coming in here giving me lectures about allergies etc...it was our choice to start her on them and we feel we made the right decision as parents.

Just wondering whether anyone noticed a big change in their babies at 4 months?

Thanks for your help
