Landon has been doing really well with potty training in the last few weeks. He stays completely dry during the day and we only have the very rare wetting accident. Problem is, he's only gone poop in the toilet two times. He waits all day to go in his pullup at naptime and at bedtime. I've tried leaving him in undies during his nap and he's stayed dry the last two days. However, we've had no success staying dry at night. This is fine, I don't expect him to pick it all up at once, but I am a bit frustrated trying to figure out how to get him to poop in the toilet. The first time he did it we hopped in the car, went to the dollar store, and let him pick out a small toy. I thought that would excite him to keep it up, but no such luck. Any suggestions?
