Being away from toddler…

A sweet lady at my church asked to have my 2.5 year old daughter a few times this week to play with her grandkids from 10-4… I trust her and would love for my daughter to have some fun with other kids.. but the only time I’ve ever been away from my daughter was when I gave birth to her baby brother last November, she was away for only 2 days and I was in labor bawling because I missed her so much… lol how do I get over the fear of being away from her?? Anyone else gone through the same thing?
