I have just found out that I am pregnant (again), I have twin 19 month old girls. They both have expressed major interest in potty training, and I would like some tips and hints for potty training. I know they say doing it before a baby comes, can be the wrong time, but I was planning on it before I found out anyways. I am only 10 weeks and am not showing at all. I have 2 potty chairs, and they can pull up and down their pull ups, and when ever I flush the potty they say "bye pee-pee bye poo-poo". When they poop they say "mommy poop" to let me know they are going, they can also stay dry for about 3 hours at a time.
