I was at my mum's today and breast feeing dd who is 13 weeks. Dd is a chubby girl and my mum suddenly says - it's so amazing that she has grown so big and healthy just from your breast milk. It was a compliment but I just think it is an odd thing to say when we are mammals and designed to feed our young. I wonder why people think breast milk isn't enough ( I know my mum was sceptical after ff her children and encouraging me to give formula on day 2 with my ds as he was starving! )
