Potty Training

Owen had is 3 year check up. The doctor said he looks great & is even smarter than most 3 year olds she has seen! She wants us to start potty training, ugh. Owen seems to be excited about it but still doesn't seem motivated. So this past weekend, Owen & mommy went out the dollar store. I let him pick out a bunch of little toys. We bought poster board & stickers. So every time that he goes pee in the big boy toilet, he would be able to put a sticker on the poster board. Every time he goes poop, he would get a little toy. I figured a little bribery wouldn't hurt. :) The object is that after a couple of weeks, if he had a n accident than we would take away one of his toys. Well it didn't go quite as well as I had expected it too. After 3 days we only have 1 sticker on the board & all toys still on the shelf. If anyone has any ideas, please help!
Taylor is doing great. She is beginning to talk a little more instead of pointing and screaming. Also no tantrums in awhile!
Daddy is good, he is looking for a new job, so please pray for him.
At the end of this week Mommy will be 30! I don't know why but I am dreading this birthday.
