date night

I want to plan our first date night since baby. She's 6 weeks old and my MIL will be watching her. Thing is, we haven't been on a date in years! I don't even know what we should do. The past two years have been spent planning our wedding, mourning a miscarriage, and preparing for our rainbow baby. I think we forgot what it's like to be a couple and talk about something other than a wedding or our beautiful baby girl. Any suggestions would be helpful and appreciated!
