Potty as a strategy - what to do?

So my son is 19 months old and uses the potty as a way to get out of situations he doesn’t like.He likes to use the potty, regularly pees in it, let’s us know when he has to go more and more often and even started pooping in the potty recently. He is still unable to remove his own pants and diaper. I do not want to do any3-days-and-done-training approach, as I believe in the slow and natural way, similar as described in RIE.Anyway, here’s my question: because of how great he is with toilet use we want to take him to the potty every time he asks for it, but because he’s a smart cookie he understood that and is now saying he has to go if we’re somewhere he doesn’t wanna be. Dinner at the in-laws: “KAKAAAAAAAAA!!!”. Bedtime:”pepeeeeee!” How do I approach this? Maybe he really has to go and then I don’t let him. Maybe he doesn’t? So far I took him to the toilet and the went back to what we were doing, but I don’t know if this is right either. What would you do? via /r/Parenting http://ift.tt/2D9tTG2
