it was all yellow

I'm trying to transition Jem out of wearing diapers at night. I probably wouldn't even worry about it except that I'm noticing that the other moms I know with kids his age aren't buying diapers anymore. It isn't going that well though. He is a really deep sleeper and he just doesn't seem to wake up in time. The one good part about it is that he will wake up after he has peed and he will change his underwear and pants by himself. He is usually doing it in the dark so sometimes his underwear or pants are on backwards. But I'm not complaining. He just lets me know in the morning that he didn't make it.
The other morning when I went in, he was laying in bed wearing a pair of corduroy pants. And not the nice, soft kind. These were stiff black ones that we only put on him when we get dressed up for Christmas Eve service at church. They are probably the most uncomfortable pants that he owns. But they were the only ones available so he pulled them on and slept in them.
I am also in the process of toilet training Truett. He just turned three and I'm starting to worry that I waited too long. He was probably ready to potty train about six months ago. He went through this phase when he would ask to pee on the potty and I would, to my shame, tell him that it was okay to just go in his diaper. Before you judge me, I was about eight months pregnant and carrying an eleven pound baby. But now he isn't showing much interest and I'm worried that I missed my window. 
The other day, I put him in big-boy underwear and we went downstairs. My mom, who was going to be watching the kids for me that morning, arrived a few minutes later. I let her know that he was wearing underwear. She turned to him and asked him if he needed to use it and he said, "No. I already went." He had already peed in his pants and when she asked him why he said, "I needed to warm up by the fire." 
I'm seeing a lot of laundry in my future.
