At what level do these measurements count?

[Guest guest]

My ortho prints out my daughter's measurements at different levels (3, 4, and

5). The numbers are worse above level 3. At which level are the standard numbers

for normal taken? Do I need to be concerned if the brachy number (CR) is too

high at level 4 if it is in the normal range at level 3 for instance? Is this

normal for the numbers to differ at different levels?

I'm also curious if babies heads get longer as they age. To me all babies seem

to have big heads, so I would expect them to elongate as they grow. From the

posts I've read though, it sounds like they really don't without a helmet or

similar.

Thanks for everyone's feedback. I'm an information junkie on this stuff. The

more I know, the better I can figure out what to do since I just don't trust my

own eyes anymore and am really relying on the numbers from the scan. I'm

terrified I'm going to take the helmet off, then realize too late that I

shouldn't have.

Oh by the way, for fun, my ortho measured my head with calipers. I think the old

statistics are right -- my CR was 76.9%!
