Don't know if this is the right place to post but here goes....
I have a 18 day old DS and today after his bath I noticed his soft spot on the front of his head was slightly sunken. Not to look at but you can feel it when you touch.
He hasn't had this before and I'm slightly worried as I know it can be a sign of dehydration 
He is EBF and fed on demand, has been feeding well today, lots of wet and dirty nappies and fine in himself, although he was awake a lot today where as he usually sleeps most of the time.
Anyone have any experience/advice? I am first time mum and not sure what to do, if anything. 
Thanks
