Hi there!
So glad your LO loves weetabix - William loves and adores his weetabix!
I'm amazed that youve read that you can give babies chocolate buttons and milky bar... not what I consider a good idea at all for such young babs - avoid that one!!!
At 6 months I was basically just offering Will cereals like rice, porridge and weetabix, pureed veg and fruit, 4 month baby jars (Stage 1) and that was about it. He started finger foods with the odd finger of toast with dairylea cheese spread on it too.
Have a look at the baby recipes section for ideas of what else you could have a go at.
Also this thread gives guidance about what to offer at what ages.
