H.B.
I did leave my children with my mother for a week. My son wasn't born yet at the time and I was scared. I haven't had the experience you have had but it was my first child and my first time having her gone for a week. What I did was set up 2 times a day that I would call them so I could check in with her. She had a great time, I had a great time after the first couple of days (which were rough and wracked with guilt). I should also mention that I am bi-polar and a control freak. I think the only way I was able to do it was because I had specific times that I called and checked in.
