I started earlier than you. My ped said anytime after 4 mos if he had all the telltale signs of being ready. When he was almost 5 mos he was just starving one day and no amount of nursing would cut it. So after a couple days of continuous nursing, we did cereal. I did cereal for a month before doing fruits and veggies, once a day for a couple weeks, then twice a day.
I started with veggies- yellow and orange. Squash and carrots. Then zucchini. I made my own food and I kinda went by the guidelines but also by what looked good in the store. I did probably 8 veggies before fruits. I started out with one meal a day of veggies in addition to his cereal meals. So I did lunch to be easy. After a few veggies, I started giving them to him at dinner too. I did the 4 day wait, so it would have been several weeks before I increased the amount of feedings. But really I just followed his cues, when he seemed hungrier at dinner I added it in instead of just nursing.
Once I did lots of veggies, I started fruits. I would then mix the fruits in with his cereal and that was breakfast. Around nine mos I introduced yogurt and would mix that with fruit for his breakfast. I still do this for my 2 year old- oatmeal and yogurt mixed with frozen thawed fruit. I use PLAIN yogurt mixed with fruit. I wanted to do as much organic as I could afford, and the cost of YoBaby was outrageous, but the big container of plain wasn't. Then I looked at the sugar content of the YoBaby and yikes! Yoplait would be better on sugar than that stuff. He has had it a couple of times when I needed something in a small container and he thinks it is pudding.
When you make your own, it takes so much longer to get through all the fruits and veggies available since you have to wait a few days. I never thought I'd be done trying them all. What I did for that was for one or two meals a day I would give him something we had already cleared, and introduce a new thing for the other meal.
I used the Super Baby Food Book. It was a great help with hpw to prepare and introduce things. I didnt follow the whole book (I never made my own yogurt-ick). But I still refer to it sometimes.
I would also go more slowly than the doc recommended, but I also started earlier. So I guess he was up to 3 meals a day around 8 mos. I think she will let you know if she wants it more often. Mine did, and I just added them in as he seemed to want them, not worrying about the time frame. We still nursed in between but had set meal times. I think I would also go slow until she is good at getting some of it in, but with my son, as soon as we did the first veggie, he scarfed it. He was the cleanest baby eater I've ever seen. Another thing that is really important to your milk supply- nurse BEFORE you feed a solid. Let her get her fill of breastmilk, then about 20 mins later do the veggie/fruit. If you wait too long between it will stretch out your feeding and drop your milk supply, and if she fills up on food and doesn't nurse as much, it will drop your supply. When first starting solids it is a kind of precarious time for your milk. So always nurse before, not after. Sorry this is so long, hope it helps some.
