Isn't it Ironic

Brandon and I are leaving tomorrow for a kid-free trip to Las Vegas. We decided that we needed some time to relax and get away before the new baby comes. We will only be gone for 5 days but we have been looking so forward to going. We took the kids up to my parents house tonight so they can watch the kids. Parker and Kamree were so excited to be staying with Grandma and Grandpa and they have lots of fun things planned. We tucked them into bed and were going to leave when we heard crying from the bedroom. It was Parker saying "I want mama and daddy." This is rare for him and so it my made me feel sad. We went in and gave them both another hug and kiss and then my mom told us to go and she would stay in the room until they were asleep. So, why when I think I need and a break and even look forward to one, do I find myself already missing my little kiddos and wishing they were here? Isn't it ironic? Have you ever felt like this? I know they will have a blast with my parents and things will be fine....maybe I'll feel better in the morning :)
