Try not to worry too much Amy. I think it is very hard to detect that early with a hand held instrument. Hugs.

Sal - ROFLMAO at the very idea of having my feral son in one of those hammocks. I love the idea of them. But I can't imagine what he would be able to get up to, the mind boggles. He has climbed out of his cot a few times but thankfully has forgotten how to do it. His fave past time when he awakes is to jump up and down, using the mattress as a trampoline. I guess in a hammock, he could swing himsefl right over LOL!
