Isaac potty training update

I think Isaac is getting the hang of potty training! Today we had NO accidents...granted, he only peed 3 times total. But the last time he came to me and said "POTTY MOMMY!!!" I got him on his potty chair and he said "Went potty in my big boy underpants a TINY bit." But for the life of me I couldn't find the wet spot!

Oh, and his big boy underpants...they are really cloth diapers. It makes his accidents MUCH easier for me and he doesn't know the difference! Oh, and they are adjustable one-size diapers so I can use them on baby too (yes, I'll be cloth diapering).

Here's the pic of Isaac taken yesterday when I asked him to pull up his shirt to show me his big boy underpants :)
