Little Bailey goes to school!

We have been concerned with Bailey and her pronunciation of words for awhile. I talked to her Doctor and he kept telling me to give it some time. Well its almost been a year and we still have concerns. I called the Up to 3 Program and they came out to the house to do some general testing. She tests great in all areas and her vocabulary came back that she tests higher than her age. But her dang pronunciation struggles. So after being tested by a speech therapist she qualified for their program. So now in the Up to 3 program she goes to preschool twice a week, a speech group once a week and meets one on one with a speech therapist once every other week. She is loving preschool, but it is really hard for me to leave her. She is only 2! I leave her for 2 hours and she does very well. I met with the teachers, watch her through the viewing window but I can't believe she is going to preschool. When she turns 3 she will be out of their program, but has already qualified for another program that will help with her pronunciation. Where did the time go? How can she be old enough to be in preschool? How did we get here already?
