Ever since we potty trained T, he went from STTN (and waking only rarely in the event of illness) to waking every night. Mostly to pee.... We still have him in a diaper because I didn't expect him to night train so soon (6 weeks) but he wakes up dry most days. He just turned 3.
When does this phase end? We have a night-waking 6 month old and this is ridiculous!
