Hi Tracey-
When I started solids, I only gave dinner for awhile, then added breakfast. I waited over a month before introducing lunch as I just felt like it was too much to cram into the scehdule. Anyway, once we had got all three going, I gave her breakfast somewhere around an hour after her morning BF, which didn't interfere much with our day. Generally I would BF at lunchtime and then give her lunch not too much later. Around 9 months I switched and started feeding her before her BF - we have since dropped this BF (actually, we went to a bottle, and then she dropped it). I kept her mid-afternoon BF (which has also since turned into a bottle) and then gave her dinner about an hour and half later, as it was dinner time anyway. Bedtime, we still BF. In a nutshell, our food schedule looks/looked like this (I'll just leave the naps out to make it easier):
7:30-8 AM - wake and BF
8:30 - breakfast
Noon - BF
12:30 - lunch (eventually I switched the two and then just gave her her bottle with lunch - now she gets water in a sippy cup)
4PM - BF (now bottle)
5:30 - dinner
7:30-8 BF and bed
This gave us a good amount of time in the morning and afternoon to get things done. I think as long as they're taking both ok, I wouldn't worry. Not sure how old your DD is, but if you're just starting solids, it's more important that they get their milk anyway.
