Hi M.,
If you daughter is eating it all and her weight is okay, then I would not worry about it. I think it is great if she is being a good eater.
When my son was that age, I gave him the following:
Breakfast - 3 TB cereal, 1 jar fruit, 6 oz formula
Lunch - 1 jar veggie, 6 oz formula
Snack - 3 ounces water with 1 ounce juice
Dinner - 1 jar veggie, 6 oz formula
Before bed - 6 oz formula
Sometimes I would add cereal at other times, just because the food was so runny.
Now, at 9 months, he eats 1/2-1 more jar at breakfast, lunch (I added meats at lunch), and dinner if that. Now that he is crawling and moving around more and all that, he is alot less interested in eating.
I got a chart from my pediatrician that says the following:
Ages 5-6 months:
5-8 Tbs of cereal/day
1 jar fruit/day
1 jar vegie/day
1 jar meat/day
24-32 ounces/day
4 ounces water/day
Max 3 ounces juice/day
Ages 7-8 months
5-8 Tbs of cereal/day
1-2 jars fruit/day
1-2 jar vegie/day
1-2 jar meat/day
20-24 ounces/day
4 ounces water/day
Max 3 ounces juice/day
Based on all this, I think it sounds like you are right on track. Keep in mind that the size of the jar increases when you go from 1st to 2nd to 3rd foods.
