We started on Friday! DS turns 3 this week and we decided to go for it now that our younger son is 9 weeks old and we feel like we have 1/2 a brain .How's it going? Days 1 and 2 went great, but we're struggling day 3 with opposition. Luckily we haven't had an accident...yet. Tomorrow we are sending him to school in underwear!!! Eeek!
