DD is a big baby. She was not born big as she was born 3 weeks early due to my complications, but she has grown and clearly now genetics have taken over (me and DH are giants!) and she is tall and built. I have only bf her up til now and she is 20 weeks. Can I realistically go on til 6 months? She is very hungry and I am very tired. I fed DS til 6 months and 1 week, but he was skinny and content to suck on empty boobs so it was OK. She is so big and I wanted to hear if anyone else had been OK just bfing a big hungry baby til 6 months.
