Feel like the worse mom in the world! Have to take my baby to the doctors because I said yes to watching her dog who apparently had parasites and more then. Likely Grayson got them :(:( all because I was trying to do a good thing and the owner of the dog cared more about her dog then my son! When she knew about the dog having parasites and didn't say a thing to me!!! Beyond pissed and kicking myself in the butt because I did this to my son :(
