danni - you can combine different vegies. they say(from books and MCN) carrots, potatoes and pumpkin are good first foods and you can combine them. you can go with any vegies, broccoli, cauliflower, even green leafs. fruits - avoid once that are acidic like oranges etc. pears, apples are ok.
ive been combining foods for lakshman for the last week. gave him pumpkin and tofu yesterday. gave him pumpkin and carrots this morning, and am giong to give him a little rice cereal this evening.
he has a breastfeed now at 5am when he first wakes up, then another at 7ish/8. then his meal at 10ish. if he has a lot then i skip his bottle till about 12ish, 1.
i dont think there;s a fixed rule when they can have 2 meals. from what ive read, after the first week you can give them 2 meals. at the end of the month, when he's been on solids for about 4 weeks im going to try lumpier food.
so far this is my plan, vegies in the morning and rice cereal in the evening. i might alternate vegies and fruits in the morning, or add vegies in the rice cereal in teh evening.
yoghurt - full fat w/o sugar, just plain is good for them too instead of custard.
i might give a teaspoon later today to see how he goes.
by the end of august, i think i will start him on 3 meals a day.
im also thinking of introducing fish in a couple of weeks, and then chicken. red meat will be harder to digest.

my friend recommended baby and toddler meals by robin barker to give you ideas of meals to make. but in a few mths they will ahve similar food to us.
