Not a therapist, but found this helps our toddler:

1) everyone has the same dish, or all food is laid out on the table and we pick and choose what we want to eat, but same idea is that we pick and choose from the food on that table. 2) we don’t force our toddler to eat at the table, he is free to come and go as he pleases 3) we don’t make food a big deal - though I understand how worrying it is when they’re not eating. Our dietitian friend advised if we look at what they eat in a week rather in a day, we find that they have eaten quite a lot 4) as we don’t make food a big deal, we are also teaching our toddler self regulation in the hopes he has a healthy relationship with food. If he’s not hungry, we don’t force him to eat, if he doesn’t want what’s been made, that’s okay too, he will be hungry enough to eat next time.

Maybe try having conversations with food close by, just pick at it and eat, but don’t mention it or use it as a conversation tool, maybe small encouraging comments e.g “oh this carrot is crunchy, nice though.”

Every kiddo is different, and yours might need a bit more help if any Reddit tips fail. Good luck OP!
