As a mom, I always felt my kids came first. As a first time Grandma, I've felt the same. My son and his wife are very choosy about who they let care for my granddaughter. They recently located to Columbus, and only have my daughter and son in law locally, and my neice, who just went through a difficult pregnancy, and has a newborn, to babysit. I have been making the trip to watch my Granddaughter when needed.
I'm sure that they will ask my niece to watch my Granddaughter, if she's able, but that doesn't mean that I don't wish I could be two places at once.At the end of the day, I will be there for CT, or go back and forth so I can care for them both. It's not just about my time, I have other issues.
