It was not luck that my parents made friends, or made the effort to develop relationships with friends that involved mutual child care. It was common sense.
No, truly, it was mainly luck.
"I just remember as a kid going to
grandparents or
aunts/uncles on the "other" side of the family when there was a big family event on one side. I remember spending the day at our
neighbor's house when my sister was born. And later on there were
playmates whose moms would have a sleepover in return for a sleepover when THEY wanted a day/evening/weekend out."
Neighbor who is willing to have a kid over AND trustworthy enough = lucky
Having relatives around and having the OTHER side of the family around = lucky.
The only thing sort of not due to luck was the parents of the playmates, but even there it's luck of the draw. I once was at a sleepover that concluded with the father raging down the stairs SCREAMING at us. No more sleepovers there. What if that happened while the sister was at the wedding hours away, and coudln't come get the kids from that? So even having playmates with parents playing with a full deck involves a bit of luck. (editing to add, that father seemed a pillar of the community, totally normal, sane...until that night...my mom totally trusted them until then)
You are lucky, your parents were lucky. Not everyone has the network to keep up, not everyone has friends who want relationships created in order to have childcare, not everyone has friends with kids, not everyone is sane. Own the luck. You guys had it.
When MY brother was born, my grandmother had to spend hundreds of dollars to fly across the country and stay for some days, and she was verbally abused by my father for her trouble. That's NOT lucky.
Lots of attitude towards the OP's decision to celebrate her wedding with adult guests in an adult manner.
The OP's whole family invites children. She is the only one who doesn't want to.
Exactly.
But I don't even care what this bride wants, but she deliberately HID her decision from her sister. I still would love to know when she was planning on sharing it, and why she thought that her sister would be experiencing fewer difficulties if told closer to the wedding rather than later. That part is very strange to me, at least, in a person old enough to be getting married.
