Thanks again everyone - DS was born 3.5kg and is now 3.2kg however he has put on 15g in the last week. The nurse said the recommended weight gain is 15g per day.
He is having plenty of wet nappies and is now settling well and seems alert when awake.
Just another question is it true that some womens milk lacks sufficient nutrients?
I am absolutely exhausted from feeding and pumping but am going to persevere if he shows a weight gain, any gain is a plus I think..
