Baby on the way and potty training a toddler?

My second guy was newly potty-learned when number three came home...we've not had any issues with regression...number two also has a big brother who is out of diapers, neither were affected by the fact that Babe wears dipes. If she's ready to ditch the dipes, I really don't see that it'd be a huge issue for her. Now, if you force her into potty-training, that might be another story...
