Good foods for upping my 9 month old's weight
So my son had his 9 month check up and the doctor is concerned about his weight. I was really reluctant to listen, I know that breast fed babies are under represented in growth charts and that they don't tend to gain as much weight as formula fed babies, so I started looking on line to show that everything was ok. I went to a couple websites including kellymom and the world health organization recommendations and it shows that my son who was born at 8lbs 6 oz, should be around 21 lbs at this point and he is only 18lbs 7 oz. My doctor wants me to add butter to his food to help fatten him up, but I was just wondering if anyone had any suggestions of better foods to use. He generally drinks around 18oz of breast milk at daycare along with about 12 oz of food. At home I breast feed about 3 more times and generally try to give him some of our dinner if appropriate. For example today he had a bannana and oatmeal for breakfast and some refried beans for lunch. Last night he had avacado for dinner. Ok that is probably too much rambling, but just looking for any ideas anyone has.
Just to let everyone know, I'm not hugely concerned over this, but after doing the research, I see that my doctor is right in that his BMI is low, and his growth is low even by breast fed standards, so I figured I could try to steer his eating towards foods that might help with his weight gain.
