5 year old angst

Dreamsicle just turned 5 and what I firestorm I have started with our decision not to have her start kindergarten this year. From the cashier in the grocery store to a fellow adoptive mom it seems as if I am breaking a cardinal rule that I did not know existed. Thou MUST enroll your child in kindergarten when they turn 5. Ready or not.
Dreamsicle is the slightest of slighty little girls that you could ever have the pleasure of meeting. She has a memory that continually amazes me. But the thing is-she is still a little on the wobbly side when it comes to things like articulation, small motor skills, etc. And don't get me started on my sweet little long legged beauty that still needs to grow into her body and be able to get it to move the way she wants it to. Add to all of this the fact that she does not have a mean bone in her body (which means that she could very well have gotten chewed up and spit out by the batch of mean girls she would have been attending kindergarten with had she started this year) and it was the right decision for our family.
It was the only decision actually.
That being said, why am I left having to defend our decision? I have honestly never heard anyone that started their child when they were six say that they regretted that decision but I have certainly heard plenty of people say that they wished they would have waited to start their child until they were six.
The thing is-so many people make comments about it that now my little Dreamsicle has started questioning if "shomefing" (something) is wrong with her that kept her from being able to start school this year. That question breaks my heart. Add this to the list of conversations I never thought I would have to have with my little girl...
