Is anyone in the situation that has been dubbed, "The Sandwich Generation" ? This term refers to those who have the responsibility for care of both their own children and their elderly parents. What have been your biggest challenges?
When my mom lived with us last year, I suddenly found myself in the "sandwich generation". In fact, my whole family was suddenly "sandwiched", down to my oldest son who shared a room and bunk bed with his grandma. Our biggest challenge was definitely space- I felt bad that I couldn't provide my mom with her own space and at the same time, we were mourning the loss of having total privacy in our own home.
Personally, my biggest challenge was the logistics of all the errands! I was already feeling like a taxi with just the errands involved with having two small children. When my mom moved in, the additional doctor appointments, paperwork, and general "running around" made things almost overwhelming. I was also unprepared for the emotions that come with being in the "sandwich generation". However, I started seeing a therapist as recommended in this sandwich generation blog post and that helped immensely.
However, even with all the challenges, there were also great benefits and advantages of being in the "sandwich generation". My kids were able to really bond with their grandma in a way that wouldn't have been possible otherwise. Just seeing them play together was enough to bring a smile to my face almost daily.
