My dad and my grandma have RLS. They never sleep. I am amazed at how my dad gets so much done every day with so little sleep every night. I, thankfully, haven't had any indication of having it. My dad was on some experimental drugs for awhile that helped him sleep through it, but he was sore as hell the next day.

I'm not a parent yet. I'll take what you said into consideration, though. I do intend on having kids one day, when my life slows down a bit.
