After a bit of trial and error, you'll find what works best for you and your LO. I always did 1 hr after breast/bottle so Tyler could get a bit of an appetite. I would have loved it if he could have taken solids right after, but it was just too much food and he wasn't hungry at all.
As for which time of day, your best bet is after the 7 AM or 11 AM bottle. This gives you all day to watch for allergic reactions or tummy issues.
