Hey there. Definitely talk to your nutritionist first. Philip is 6 months and I breastfeed too. We started with rice cereal last month which he flat out refused (he has a taste for applesauce
We then moved to jarred rice cereal with applesauce and we add 1 SCOOP of formula to 2 tbs cereal. He is on the verge oof being overweight (well, maybe he is), but they want him to be for his lung health. Two weeks ago, we started real food. We started with sweet potatoes, and I make all of his food so I know what is in it. I also do not use water when I make his food. I add breastmilk. It gives calories and it makes his food sweeter. The nutritionist told us by 8 months, he should eat 4Tbs cereal 2x/day, 4Tbs veggies 2x/day, and 4Tbs fruit 2x/day plus about 30 oz breastmilk. That's a lot of food! Anyway, whatever you do, keep track of everything that goes in Sam's mouth so they can reevaluate if he isn't gaining appropriately. Please PM me if you want to know more!
