Do you worry about their safety?

My lo is staying at my parents house this weekend while we go away to celebrate our anniversary. I have been away and my husband has been away but we have never left her with someone without us. My parents are totally capable people but I worry that they will leave a door unlocked, our lo will wake up early and go looking for us and wander away.

Ugh. How do you stop worrying and know that your lo is in capable hands when you go away together?
