HI,
I think she was about 8 months when she went to 3 bottles. for your schedule 7,11,3,7...I would do the solids at about 5pm.. (I do remember doing this now!! It is so hard to remember sometimes!!!) We introduced Jasmyne to solids early.. she ate prunes at 8 weeks and was on pears and sweet potatoe/squash by 6 months... introduced chicken at about 7 months and beef at 9 months. Her stomach did really well with all the new foods. You just have to go with what you LO can cope with. Everyone will have their own recommendations, but your childs reaction will let you know if it is too much too soon.
Whatever you do make sure that you do not overfeed the solids as their little tummys need time to get used to processing the food, so just a little bit everyday is good!! Also remember that when you do introduce a new food stick with that food for 3-5 days to make sure that you don't introduce too many new foods at the same time.
By the time Jasmyne was 9 months she was eating 3 meals a day although the "lunch" was really a small snack, e.g a little yoghurt or cheese as she was still getting a bottle at about 1pm..
her schedule was
7 bottle
9 breakfast
9.30 nap
11 yoghurt
1pm bottle
1.30 nap
4.30 dinner (chicken, sweetpotatoe and brocolli)
6pm dinner
Let me know if you have any more questions!! I am not an expert, but maybe can offer some reassurance!
