The kids spent a night with grandma and grandpa earlier this month. This was an exciting event to them, because although we have all slept at grandma and grandpa's, I can only remember one time that Conrad stayed there without Tim or I. And that may have been even before Norrie was born? Regardless, this is something they had been asking and asking for.
And they weren't disappointed. It sounds like they had a wonderful time. They are looking forward to baby's arrival because it might mean another overnight!
