yes, i don't think the 5 fruit and veg thing is necessary yet. is he still having plenty milk?
dd is 8 months. she has porridge or cereal for breakfast, or banana on toast. i try to only give bread once a day (salt content).
lunch is usually something sandwichy (humous, cheese spread, hard cheese, tuna)or something on toast or an omelette if we had toast in the morning. i put veg in the omelette (peas, broccoli, potato). then she has piece of fruit for 'pudding' (usually pear, peach, nectarine).
then tea is more like a proper meal, pasta, fish, always with at least one veg other than potato. we don't eat meat.
snacks are usually fruit or organix snack things (sweetcorn rings/carrot sticks/rice cakes).
basically, she has what i'm having, so if that is 5 portions of fruit and veg then that's what she has. however, some days she doesn't fancy much, so she has lots of milk.
