"I'm a big kid now"!!!!!

So on Monday as you all know Ayden turned three!! He slept in later than normal and when we FINALLY WOKE UP(I was like a little kid  ) He woke up in such a great mood. I told him HAPPY BIRTHDAY!!! and then I ask him "Ayden, are going to be a big kid now and start going on the potty?" and He said "ya mommy I'm going to wear underwear". So all day monday he wore big boy undies and we only had ONE accident and we changed him and went on. Then when he got ready for bed I asked him if he want to wear a diaper and he said no he was a big and so he went to bed with undies on. Woke up he was dry and today we did good almost all day. So hopefully he is on the right track to being potty trained. GO BUG GO!!!!!!
