First: Learn to count higher, much higher. In my experience, this ain't no 1,2,3.
Second: Teach your child to change their own diaper. Yeah, they don't like it either.
Third: Encourage your child to always seek out your spouse for the needed diaper/pull up change. If this doesn't help enlist your spouse's potty training assistance at least it will spare you some diaper changes.
Fourthly: Don't give up. It will happen eventually.
Fifthly: Try bribery. Chocolate and stickers can work wonders.
Sixthly: If your child has successes after coming home from someone's house, send them back there often.
Seventhly: Don't give up. I know that was number 4 but sometimes you need a reminder.
Congratulations, Noah, on your achievement!
