G.M.
I've been flossing between my 2 year old daughter's teeth for well over a year, per her pediatric dentist's recommendation. We use one of those little picks too. I noticed the dentist getting kids to open their mouths by saying he's got to get the little bugs out of there. So we make jokes about monkeys being in there and making monkey sounds or whatever animal we think of. I tell her they're asleep, and we've got to wake them up and tell them to get out of there. She thinks it's funny and usually goes along with it. Being that she's 2, we've had some issues the last week or so, so I tell her I will let Santa know she's not being a good girl and helping Mommy. That usually straightens her right up. LOL Good luck!
