My son started daycare around 9 months too. It was harder for me to leave him at daycare than it was for him to watch me go! We also went through a transition period at the beginning and it really helped.
I remember the first day of handing him off at day care. I was a mess! I was only leaving him there for about 90 minutes, but I felt awful like I was abandoning him. I cried as soon as I got into the car and felt guilty the entire time I was away. Upon my return, there he was bouncing away in the exersaucer having a grand ole time! It was then I knew that he would be okay. Over time, he has grown to love his caretakers and we even call his main teacher 'Grandma Karen'!
I can assure you that this is normal and would happen whether your child was at a center or an in-home. One thing you can do to help your child is to establish a consistent but concise drop-off routine. Take him in, give him a hug and a kiss goodbye, and promise that you will return later so you can hear all about his day, then leave. Lingering over the goodbye, crying and making it dramatic will only cause more tension and anxiety for the child.
Now that my son is 16 months, we still have an occasional meltdown at drop-off. I get into my car, peek into the window, and he's already calmed down and exploring the place for the first basket of toys he can pull of the shelf and dump all over the place. If you are feeling apprehensive, call the center 15-20 minutes after drop-off and ask them how he's doing. Just continue to reassure him once you get home and demonstrate that you will always keep your promise to 'return' to him once the day is done.
And by the way, my son has never once had to 'cry it out' at daycare. If your daycare does that, then you may want to consider switching.
