Archie eats almost everyting and anything!

Some snacks he has is

crumpets with honey or jam
vegemite and cheese slice sanga
dry cruskits
chopped up fruit - strawberries, grapes tomatoes sultanas raisins kiwi banana
yogurt
custard
jelly with tinned fruit in it
cheese sticks
cheese and bacon muffin
museli bar
rice crakers
tuna pasta bake
tacos and burritos (his fav dinner as he can pick what he eats and how much he eats)

when he was just starting on different foods i found large pasta spirals with a little bit of pasta sauce or tomato sauce was good. i was quite stressed over what to give him when he first started but all the suggestions on here really helped me.

Regarding the bottle of milk, have you tried giving him a drink of water out of your cup? It is messy but Archie loves to have a 'big' drink.

GL i hope he stops being fussy very soon.
