We've given them our food from 6 months onward. They had Xmas Dinner for instance when they were just over 6 months old - Yorkshire pud, gravy the lot!
I've avoided honey for the infant botulism thing.
We don't really have gravy as such but there are stock cubes in loads of recipes. I cook everything from scratch anyway so I never add salt and I count the stock cube as salt. My HV said not to worry about a bit of gravy anyway and they've been fine.
Mine eat all sorts of fish - Mackerel, pilchards, sardines, white fish but I haven't given them prawns or shellfish of any kind. I'm thinking of doing a paella next week so that'll be their first taste of prawns. They've eaten all kinds of meat including liver which they loved.
We don't eat chips so they haven't had any - I suppose they might have had one once but can't honestly think where! They eat plenty of cheese. Yes it is salty but it's good for the calcium and protein.
Jars, packet mixes and processed meats like sausages, bacon and ham probably have a lot more salt in them than you realise. Skip the packets and jars if you can and use the bacon and sausages sparingly.
Mine have had chilli and curry and have been fine so don't worry about herbs and spices. Just go easy. I wouldn't start with a vindaloo for example!
Mine have had eggs as omlettes and scrambled. They're not mad keen on them but they do go cold quickly and frankly I like mine a bit on the runny side rather than the leathery side which is how they come out fully cooked. They like an egg mayo sarnie though.
