As another stressed out mother, I feel your pain.
My son is almost 5 and meal times have been a battle from when he was about 1 year old.
It takes about an hour to eat a meal, and that is filled with blackmailing, anger and desperate pleas…..just anything to try and get him to eat.
He’s on the 12th percentile for height and weight so it’s not particularly extreme but he’s so obviously much smaller than his peers.
We find that letting him watch videos/TV to distract him is the best way of getting food into him but I’m aware it’s a bad habit to get in to, and it also means I’m either having to constantly remind him to eat or I have to feed him.
He prefers bland food but he will eat curry and lasagne and other home cooked meals when pushed too.
I think he has a bit of a sensory issue going on as he can gag on food quite a lot, sometimes to turn point he vomits - but that’s very, very rare.
I know it must be behavioural because he’d eat chocolate all day long if I let him.
His childminder has expressed concerns about his eating and says it’s getting worse. I’m dreading him going to school.
I don’t really have any words of advice because there’s nothing I can suggest that you’ve not already tried or are already doing.
I just wanted to let you know how sorry I am you’re going through this, unless someone has a true ‘picky eater’ they cannot understand how emotionally worrying and draining it is.
If you have the funds then I would pay to do private to see a SALT and/or dietician. That’s what me and my husband are nearly at the point of doing.
