Garrison really started kind of potty training himself a few months ago. I think it was because he lives in a houseful of older people that use the pot; so he wanted to be like us. He's to the point where he only messes himself when he's having problems and can't make it in time. He's still very inconsistent with the wetting, but we are happy for the progress he has made.
This past week we tried underwear (before we were just doing Pull-Ups) He had a lot of wet underwear, but I think it was helpful for him to have that immediate knowledge that his underwear were wet. For now we've went back to the Pull-Ups because he has been having problems getting to the pot on time for his messes. We're cutting back on juice and such to get him back on track.
Anyway, I really doubt he'll be completely potty trained when this baby comes, but I think things will be a little easier and he'll be well on his way. All my other kids weren't done potty training until they were 2 1/2 or older; so he still has a few months.
I took some really cute pictures of him on the pot! (good blackmail material when he's older!) Notice the cute afro ( I guess afro is not a word, oh well)? Daddy actually cut it off recently, but I just love his hair!
