How to get toddler eating healthy

[MyBrownEyedHandsomeBoy]

Has anyone's DC just miraculously started eating fruit and veg?
I think a lot of the problem with mine is that when I was weaning him, I was advised not to give fruits and certain veg because he suffered with severe diarreah due to a lactose intolerant (dietician advised to wean from 5 months on starchy foods until his stool had firmed) so I introduced fruits later and he's just never taken to them.
He's 2 and half now and still to this day will refuse. Most his meals are still starchy (waffles or chips with fish fingers or fish cakes etc) if I put peas, brocolli, or any sort of veg on it gets left of thrown. If I offer grapes, strawberries, apple etc he won't even try them and will scream if I go towards his mouth with them (almost like a phobia!)

Has anyone got any tips? I've tried covering them with chocolate even. Just licks the chocolate off and disregards the fruit. I am so worried he's not eating healthy enough.

Keep offering (definitely not covered in chocolate) alongside meals, it will take time but let him have the chance to pick up, feel and hopefully taste them. Don’t put any pressure on him or mention it. And slowly reduce the processed food and replace with meals which include some veg already like a pasta sauce with veg chopped in it.

Keep offering. On the plate, every single time. Dont talk about it, do not encourage. Just leave it on the plate.

There are guides on how to introduce veggies where the first stage is completely blended in a pasta sauce, and the next stage is a little more roughly chopped etc. My DD went through a stage of hating all veg but was absolutely fine with homemade soup and pasta sauces.

One day she just picked up the cabbage on her plate and ate it! Toddlers are funny things.

Keep offering. Small amounts so not wasteful in pots that interest them like a wee dinosaur cup. One day it will happen.

Also being around older kids they want to copy are fantastic for subtly introducing stuff. Maybe get a windowsill plant for tomatoes too (or something).

SR Nutrition is great. She has an Instagram where she answers questions every Monday, and does lives sometimes.
This is her blog on the subject, mostly still applicable to you despite the weaning issue you mentioned

I used to make pizza with mine and lay out some veg for toppings. She would inevitably 'steal' a bit while we were making it, just out of curiosity. It didn't immediately translate into her eating tons of broccoli but it meant she tried different things. Lack of pressure is the key thing.

Also: almost all vegetables taste nicer with a bit of pesto or cheese (or both!). Plain, steamed, unseasoned vegetables in general aren't very nice.
