Need some advice on potty training two toddlers

boy or girl

Both, my biological son and my foster daughter .my son is so strong willed and is giving me such a hard time. And my foster daughter is excited to start but I don't think she's ready yet.they are both 2

I've tryed everything with my son, I'm about to skip him and start focusing on my baby girl

Feel like giving up sometimes

ok with my son i first started at one that didnt work so we started again at 2 it was hard but he got the hang of it he was fully trained when he 3 ... lots of hard work

for my daughter we did a prize box i got a shoe box made it all cute and girly and put a bunch of lil dollar store toys and whenever she went potty she can get a prize

we also sang and danced after she went potty and she loved it
