I'd avoid cornstarch on P1. When I need a thickener, I use arrowroot or I just omit the thickener completely so that a substitute wouldn't change the taste. When you have a thin sauce, maybe you can double it and let it reduce in a pan.
I use chili-garlic sauce instead of sriracha because it doesn't have sugar, so without knowing how different sriracha is, I'd just add a touch (maybe 1/4 tsp) for flavor but less spice.I'd try about 1-2 tbsp peanut butter, 3-4 tbsp soy sauce, 2 tbsp rice wine vinegar (can substitute white vinegar or water), 1/4 tsp of chili-garlic sauce, and 1-2 minced garlic cloves. I'm guessing since I improvised last time I made something like that.
You could start with the smaller amounts and adjust upward if it's not enough. Also, instead of doing the sriracha or chili-garlic sauce, you could add crushed red pepper flakes to your dish, that way yours can be spicy without making your toddler's spicy. You won't need a thickener.
