I was initially concerned about it, but it is very quick and it's ONLY for diseases that:
1. are degenerative (so, the sooner you catch them, the better your chances are)
2. are very severe (and may result in the worst-case scenario).
Because of that, I decided to do it. We didn't do vit. K for our girl or eye balm, but I did that just in case. I'm glad. When we got the results it was just, great, now if there's any small thing, we won't have to worry it's a sign of those. It was just one thing not to worry about. Baby seemed far more disturbed by band-aids than the prick!
