Rylie's 5 year check up

Rylie had her 5 year check up last week. Everything went well. She is 39 lbs and 38 3/4 inches. The pediatrician and I discuss what specialist Rylie should be seeing yearly. She doesn't see the need for Rylie to see the GI doctor anymore since she hasn't had any problems since birth(anal stenosis). Every year I take Rylie to see the GI doctor. He hardly even looks at Rylie, then he ask me a few questions and says,see you next year. It's just a waste of time. I was also wondering if Rylie should be seeing an orthopedist, but the ped said not unless there was any concerns which there aren't. She just needs to have her neck X-rayed for AAI. She will need to get this x-ray again this year. Last time she had it done she was 3 years old and all was well. So now once a year she will need to see the eye doctor. And I want her to see the ENT every three months. Thats not bad. I'm very thankful!! She also got her annual bloodwork done on monday. They tested her CBC(red and white blood cells), and Thyroid. The doctor called tonight and said her only concern was that her MCV levels were slightly elevated. Normal range for her age is 73-87 and Rylie's were 90.9. This could mean a vitamin deficiancy, in folic acid or B-12, but it's unlikely in a child unless they never ate meat(which Rylie does). Then she said Rylie's levels have been at 90 for the past 4 years so its probably just normal for Rylie and thats just how she is. WTH! I didn't know that. Every year the pediatricain calls and says Rylie's bloodwork came back and everything is fine. I never ask for numbers, but I guess I should start. The pediatrician said to just start giving Rylie a multi -vitamin and we will have her bloodwork done again in three months. I'm not worried, but it's funny because I GOOGLED causes for elevated MCV levels and it came up Down syndrome. Is this something comman with Down syndrome?
