Potty training twins??

I have 3yr old twin girls. I recommend buying 2 potty chairs, because the moment one child announces she has to go to the potty the other one has to go too. Let them pick out their own so they will have their own special one. When I first started introducing the potty I put it in the corridor just because it was more convenient. Though they prefer it to be in the bathroom so they can be like mommy. The best advice for you potty training them is just to be patient, and realize they both may not meet your goal of doing it by Feb. And give them allot of praise when they are doing good. Good luck.
