I realize that I might not be saying the popular thing here...but I don't necessarily think that cutting back on solid food is the answer. At some point babies will switch over to solids as their main source of nutrition. It should be a gradual process and won't magically happen over night. I know that BM should make up the majority of calories and nutrition for the 1st year...but if you don't offer food then how is that switch going to be made, KWIM?
Its hard letting go and realizing that our babies don't need us 10 and 12x a day to nurse. But that doesn't mean we should try to stop that natural process. I would just always offer to nurse your child first, before any solids, and then offer and ALLOW your child to eat however much they want to eat. Let them control their portions...you control the choices and make sure that you are offering healthy, nutritious food.
It was hard for me when I realized that my child was ready to give up some nursing sessions. He eats 3 meals a day, 2 snacks a day, and nurses anywhere from 3-5x in a 24hr period. Its ok to start to let them go a little! I can tell you that my guy can put away WAAAAAY more than 3-4 tbsp of food...even at 8 months and especially now at almost 11 months.
For breakfast he ate 4oz of yogurt, 1 medium banana, and 1 piece of toast...all after a good long nursing session. grapes and raisins at 1020 am. nurse at 1145am. peanut butter and jelly on wheat, black beans and brown rice, cheese, fresh strawberries, and tomatoes for lunch. nurse at 315pm goldfish and raisins at 330pm (not the best, i know) nurse at 615pm and cheese ravioli with spinach and a 1/2 a peach for dinner. nurse at 10pm.
I just wanted to write all of that to say that we've all BTDT and its hard...but I just wanted to encourage you that it is perfectly normal.
BTW...all of the times that he nurses during the day (except the first one) are less than 10 minutes long. And I did for a long time try to cut back and even eliminate solids for a while to try to get him to nurse more and longer....it didn't work and I just had to realize that my baby was growing up and not needing him as much as I needed him to.
