So we finally made the switch to full time underwear on Sunday--LO had been consistently using the potty at home while naked, and was able to hold it for long periods of time.

So since he's been in underwear, he's done pretty well--two accidents Sunday morning, but none the rest of the day, none yesterday, and none today. HOWEVER, it is REALLY difficult to get him to go on the potty. He will scream and cry if I try to get him to sit on it, even if I offer rewards/bribes/etc. For instance, he peed on it at 7:40am today, and we left the house at 10am. He refused to go before we left--huge tantrum. And then he held it until 11am, when he used our travel potty.

Basically, is it ok that he is doing this? I feel like it's not good for him to hold it so long...and I also thought that they should be getting into a routine of going at wakeup, before meals, before nap, etc. But he just refuses. Any thoughts?

ETA I should also add that sometimes I REALLY think he needs to go--he'll be grabbing his crotch, etc. But still refuses.
