Every year my parents travel to Arizona and Mexico for a few months. I have two daughters now 4 and 2. The past years the girls were too small to know the differance that they were gone, but now they ask for them almost every day. It is breaking my heart to try and explain to my 2 year old why she can't see Grama and Papa. This is the first year they have been gone for almost six months (missing halloween and christmas ) I feel they are being selfish going for so long. I really want them to have a holiday and enjoy themselves, the work hard all year and deserve it but isn't 6 months a bit much. The are in their 50's and I feel the kids will only be this little once. These are the only grandchildren they will ever have, seeing how my only other sibling doesn't want kids. I would really like some input. Am I being selfish or what?
