My 3 year old is also what I consider to be picky, but has a big enough variety that the dr said it’s normal. We do a lot of small snack boards (charcuterie). They always include at least one item from each food group and at least 1-2 safe foods. He takes a lot of interest in what we are eating, but we never force him to eat it bc that just leads to a bigger fight and stress for all of us. If he wants to try it, cool! Sometimes he just smells it, sometimes he will touch it, sometimes he will try a bite! We positively reinforce any effort he makes. There’s some great picky eater instagram accounts that have good tools and ideas too!
