DD2 has woken up this morning with a visibly sunken fontanelle.

She's been off her bottles for about 2 weeks now, I'd be lucky if I could get 50 or 100ml at a time into her. I'd keep trying but she would just get cranky at me for trying to make her drink. So I didn't force her to drink them. The most she would drink would be about 150ml of her night time bottle (she usually has about 220ml each time)

She has been drinking a little bit of water, not much cos she is still learning how to work her sippy cups at mealtimes.

So today, her fontanelle is sunken and it seems like its a bit sticky? Just in that one spot? And looks like it was wet and has dried? Its very strange.

If she was younger I'd be going to the doctor or something but since she's acting pretty normal - she's happy, laughing, cheery as anything this morning - is it ok or something more sinister?
