Fitbit Flex is a no go

I found my Fitbit but I'm not going to be able to use it right now. The metal band seemed to work okay but I didn't like wearing it because it caught on my son. I tried to go back to the regular band. Sadly, I broke out into a rash again. The metal band is very pretty and I found it on Amazon.

The band I used was the a standard Fitbit Flex band. 

And this is the rash I broke out in. 

Once my son is a little older, maybe I'll try to use the metal band again. It's just a little too bulky to wear while he's so young and needs to be held all the time.
