So my DD is a picky eater and over the years I’ve come to find that, things she was crazy about just that morning she now hates, I can ask her if she will eat the food and she’ll say yes and it will arrive and she won’t touch it and then proceeds to eat my meal! She claims to be full and then will beg for cookies, etc.
At home these games don’t fly, no dessert without dinner, you must try your food and have 3 bites before I’ll make a secondary dish (and really that is for when DH cooks something that’s Different from the norm - like Indian and if especially it is spicier then he thought it would be, this happens a lot actually)...
On vacation especially at Disney I relax the rules, do I get real food for the kid, yes, do I demand she eat it, no. Does she sometimes get dessert without really eating the meal, yes. That said we do very short trips to Disney so this is a day or two, not a week or two. I’m not sure I’d be this relaxed for a super long vacation but since that’s not how we do these trips I don’t feel like food is the best thing to battle over for our short annual (or every 2 years as it’s been recently) trips to the park.
Also, I find that when she gets hungry that plate of chicken nuggets she hated the night before she will devour when she’s actually hungry...
