ASHM,
for Ikea meatballs, I only restrict about 2-3 at a time..no la, it's not saltish, usually he eats with rice and flushed down with home cooked soup or water. I also let him try chicken nuggets for the same reason of letting him practise chewing..I baked them at home, never let him try those in fast food restaurants. For fries, I will order the non-salt ones when I'm outside. Basically I'm quite laxed in the food he takes, as long as in moderation will do. Just last Sunday, we had cereal prawns, I let him tried the cereals (got chilli padi and curry leaves), he also eat and asked for more..hahaha.
