OP, humans have been raising their young for 300,000 years - please don't stress out about doing it 'by the book' and end up getting overwhelmed, it just isn't necessary! There are a few important things to remember:
Limit salt and sugar (just leave out stock and added salt when you make the meal, and you and your OH can add yours at the table if you like. Avoid offering baby sticky toffee pudding and Mississippi mud pie, but a little Greek yoghurt and fruit if you feel they should have 'dessert'
Avoid bones and hard, round pieces that could stick in baby's throat, so steam any veggies and cut into batons rather than circles. Sausages, grapes and raw apple are buggers, so should be peel and sliced very thinly before being offered
Some things will 'get things moving' for baby, like apricot, pear and prunes - helpful to know if they're ever backed up but don't offer to routinely otherwise or you'll get interesting nappies!
Purees are fine, baby led weaning is fine, a mixture is fine. Just go with whatever
Pouches are very convenient but they can be sneaky! They mix fruit into savoury meals, which sounds nice and healthy on the packaging but is a way of subtlety sweetening their food so baby will prefer shop bought over yours! Just something to be aware of. Also know that shop bought 'baby snacks' in little packets aren't great. Ok in an emergency but real food will always be preferable.
DON'T WIZZ UP POTATO! It'll turn to glue. Just mash it instead.
Baby will make it clear when they've had enough, so don't get upset or resort to doing silly tricks and shoving it in when they're distracted. It's really important for little ones to learn the connection between being full and stopping eating! If they're too full of milk they won't want food, so swap round the order of bottle and meal if necessary.
Supermarket eggs should be fine to offer soft boiled but farm stand type eggs you should only hard boil or use in baking for the next few years due to salmonella risk
Honey, whole nuts and crazy weird stuff like swordfish should be avoided the first year or 2
Baby will show more interest in food if you eat at the same time. They'll always prefer what's on your plate to theirs, even if it's the exact same thing. That's just the way it goes!
They will drop their utensils and big pieces of food everywhere. I recommend a clean splat mat under the chair so you can just pass it back without worrying about bacteria.
Yeah, just don't stress! Relax and enjoy the weaning process, and take plenty of pics of them with yoghurt smeared into their hair so you can embarrass them on their 18th!
