Hi Pat,
My lo is 6 1/2 months, and we introduced rice cereal at 5 mos just once a day for breakfast. At 6 months, I added cereal in the evening, along with fruit (she LOVES her pears!), and then after about a week, I added veggies for lunch. So, she eats 3 meals a day-cereal and fruit in the morning, veggies for lunch, and cereal and fruit for supper. We are on a 4 hour eating schedule, so this is how our day usually looks:
7:00-bf
8:45-cereal/fruit
11:00-ebm (she goes to a sitter during the day)
12:00 veggies
3:00ebm
5:30 cereal/fruit
7:00 bf
Since she eats every four hours, it really has worked out well, because she can have her solids almost halfway through, so she's hungry enough to eat, but also has time to get hungry for her breastmilk. She has been cutting back on the amount that she is wanting to eat at her 11:00 milk feeding, and I have read from lots of others on this site, that the 11:00 feeding is usually the next feeding to go. So, I think in the next month or so, she will probably be down to only 3 milk feedings a day, maybe. I hope this helps!
