Well, we got a little off track, but we are back on the wagon now. Waiting for DS to self-initiate the pottying was resulting in several pairs of wet training pants a day, and only one or two successes. So, I put him on a timer. Every hour, he sits on the potty and usually something happens right away. If not, set the timer for 15 min. and repeat until something happens. Then we have these "miracle moments", like when we are about to go bed so he is wearing a pull-up, and he says he needs to go potty. And we're like, yeah right, classic stalling technique. But we let him get up and he goes! That's happened like three nights in a row. I think most of the day he is distracted and not paying attention to what his body is doing.
I must brag on my husband, he is certainly helpful with the potty training this time around. Yesterday we took the little potty to our relative's house, and though DS was wearing a pull-up, DH made sure he made trips from time to time.
And we bought Wiggles underwear today. I tell him he can wear them when he stays dry all day. We'll see if it helps.
