Dd is 9 weeks, totally breastfed on demand and seems to be growing okay - she has a bad cold at the moment and has been sick, after feeding, a few times. Dh mentioned that he thought her fontanelle was a bit depressed. You can feel the edges of the fontenelle really easily; however, she is doing lots of wet nappies, blowing bubbles and eyes seem bright and shining. So, do I offer water, or keep offering boob for extra drinks?(have done this for last couple of days, no change in the fontanelle).
