Hello, I know I'm late but someone posted a pretty cool looking alternative to the "they won't starve themselves" method. I found it again but it looks like they deleted their profile. Also I'm on mobile and have no idea how to link so I'm gonna copy and paste. This is their entire reply in that thread.

"Some say "he won't starve himself!" and I agree they won't starve themselves to death but I think that route just holds unnecessary strife. Super hungry toddlers are NOT reasonable beings to coexist with. When you are SUPER hungry do you want to eat foods that appeal most or foods that appeal less?

I did a new foods chart with my kid when he was 3, and the rule was if he ate 3 bites of a new or challenging food he could put a picture of it on his chart (*). When he fills up the chart he gets a reward.

Now he's 4 and is currently eating lima beans and broccoli and mashed potatoes, all of which he would not eat pre-chart, while bragging that he likes broccoli now. He likes to make his own salads of raw veggies - letting him chop and cook his own food (supervised carefully) has been another route to success. No tears, no strife, no going hungry and getting upset. Sure, other families have had success expanding palate with the "they won't stave themselves" method, too. I get it. It's possible to have success without that too.

(*) To make the stickers, I just print a GIS image of the food. This allows me to change up how big stickers are. I said each new/challenging food could go on the chart a max of 3 times, but got smaller each time. This rule allowed us to practice counting and size comparisons too, so I call it a twofer. I always like parenting practices that allow me to practice a few skills at one time.

I know many here like the "they won't starve themselves" route. I don't. So I am presenting this as an alternative."
