I know all kids are different, but now I'm starting to think I'm not feeding my little guy enough! My son is 9 months as well. A typical day for us: Nurse when he wakes up, then about an hour later one jar of fruit. He nurses about an hour and a half later before the morning nap (which is normally only 45 minutes??). Lunch time is a veggie and sometimes half a jar of fruit. Nurse before the afternoon nap. Dinner is 1/4 cup of cereal mixed with breast milk/formula plus a veggie and whatever is left from the morning/noon fruit. Throw in some cheerios during the day... then another nursing session before bed.
In sum, my guy nurses 4-5 times a day. 1/4C cereal and approximately 3 jars of food a day.
I wish kids came with instruction manuals! I'm looking forward to reading the other responses too!
