My baby is 6months and weights 15lbs. He was born at 5lb 11oz. I have breastfeed exclusively. He eats about 8 times a day about 4 times are at least 20 minutes and the 4 are about 10mintues due to the fact that he becomes distracted. He eats solid twice a day for lunch and dinner. The doctor had suggested I eat more fatty food and drink more liquids. I did what the doctor suggested but he only gains 2lbs like the previous months. I don't know what to do. I'm thinking I should give him formula. However, I was planning on breastfeeding for a year. Can someone help me?
