I really wouldn’t worry about the endo’s. Your main concern is your child. As Jenni said you obviously weren’t happy with the current endo. I would just stick with the new one if you feel more comfortable with  him. What to tell your old doctor...nothing...cancel your appointment and move on. I suppose if you feel some loyalty to him then call him and tell him that you decided for whatever reasons that you are going to switch.

Good luck,
