We started potty training Big Boy a week ago.
(Big Boy's face when he tells me 'no' he doesn't want to go potty)
Last Monday we went from diapers to underwear, which we went to the store earlier and let him pick out (he got cute little Mickey mouse ones!). We also got a huge family size M&M bag, as a reward for when he goes on the potty.
Kiki has been doing so good with being a supportive big brother, and keeps reminding Big boy that he needs to go potty, and yells 'Yeah!' every time he successfully goes on the potty. (I think he has realized that when he helps he gets M&M's too..)
The last two days have been relatively accident free, that is of course with the exception of going #2 on the potty... he hasn't wanted to do that yet..
Hopefully next week will be even better!
