My ds1 has had lots of issues affecting his feeding ranging from reflux, colic, constipation etc etc. Over the last couplde of weeks his intake of formula has decreased to approx 450ml in a 24 hour period and according to all recommendations, it should be more. He has a frequently indented soft spot on his head and has been waking up moe often in the night but still does not hardly eat anything. I am worried he will get dehydrated...any suggesstions/advice?
