I also meant to say to your other question about how many times a day. At first I did it in the morning, like you are, then about a couple weeks late I added it for after lunch, then after supper. I kind of based it on my own child. My daughter took right to eating solids and didn't drop her intake in milk, you don't want them to drop their milk intake at this age, so I continued to give her a bit more over time. My son on the other hand hated purees and stayed on formula only until 7 months. Just don't let the solids replace the milk and you'll be fine.
In regards to what to feed them it sounds like you have been doing well. I also fed them anything that wouldn't cause an allergic reaction. Good is Sweet Potatoes, pear, squash and carrots. Then I moved onto peas, beans, peach. Just remember to give them one new food a week, just in case they have a bad reaction.
