Thanks EveryoneTalk. I've done the first aid course and it's more like a background worry rather than the main issue. I think I'm more just stuck in the rut of thinking she's just getting used to food when at 18 months she's been eating solids for a while now!
I think I panic about too much sugar or fruit juice acids etc to the extent I avoid it rather than sensible moderation 
Typical day now:
Breakfast - weetabix, porridge or sometimes some Cheerios (but not as a regular thing), banana or she loves the Aldi's fruit pots. She's very funny with textures of things so fresh fruit is really hit or miss
Lunch - bread or toast, babybell, most days she has home made soup, occasionally pasta, loves avocado, yoghurt.
Dinner - pasta, spaghetti Bol, sausage casserole, cooked chicken etc. At least one or 2 'extra' veg portions by self to nibble on, loves broccoli.
She eats pasta, rice, spaghetti and sweet potato but changeable with textures so sometimes mashed gets abandoned sometimes she prefers it to chunks! Then more fruit or a mini custard. The dinners are home made about 70% of the time she eats the odd toddler meal packet
Snacks - veggie crisps, toast, grated cheese, banana, mini oat bars, fruit chew things. She drinks water and milk.
I think I've just been a bit OTT with thinking ok avoid this, avoid that and it's kind of just happened and the worry I'm 'doing it wrong' is a bit limiting
I would love her to eat more fresh fruit and veg but way back at start of weaning I was worried her reflux would be triggered so was very cautious about what I introduced and when
Sorry for the HUGE reply!!!
