I find the role of grand-parenting somewhat confusing.
My two sets of grandparents had huge families so I have over 80 FIRST cousins all together. I was lucky if my grandparents could remember my name, never mind have any relationship with all of us. I don't remember them well because all four died by the time I turned nine-years-old.
I moved 750 miles from my hometown when I married for the first time and I had my oldest when I was 21. I lost my mother when I was ten-years-old so my children were already down a grandparent but the other three lived far away and we only saw them once a year for a week.
I moved to England for my second marriage (I am in the US) and had two additional children there. My in-laws lived 200 miles away from us so we saw them every few months for a weekend.
My husband was based in Europe so he moved our family to be closer to his parents and ended living four miles away from them. I saw my in-laws every week and it was very nice for my children to have a grandparents in their lives but that only lasted five years because we ended up moving to the US.
We returned but again we were far away from my father so we were back to being by ourselves. My father passed away nine years ago so my children only have my in-laws as grandparents and they are in England and quite far away.
I became a grandmother a week before my 42nd birthday and again to twins near my 46th birthday.
I adore my grandchildren but I never know exactly how I am supposed to act that will placate my son. If I want to spend time with them every week, my son says I'm asking too much. If I don't see them every week, he gets angry that I don't spend enough time with them.
Last year, the whole grandparent scenario changed entirely.
My son and the children's mother made some ridiculous life choices and I ended up with a year-long temporary custody of my three grandchildren. They were with me 24/7 for a year. I love my grandchildren but I have found caring for them extraordinarily difficult. I had to "raise" them. I feel like I felt every single day of my 49 years. The year long custody has ended so they no longer live with me but they are not living with their parents either. I miss them every single day but I don't think I could do the day-to-day care again.
I've had two very extreme experiences. I hardly had grandparents in my own life; my children had limited experience in theirs and now I've been parenting my grandchildren and now I don't have them.
