Both; being the oldest or the youngest child have their advantages.
Being either of the two also carry disadvantages as well. Being the oldest for most families I know, including mine when I was a kid, involves having to look after their younger siblings, which could include a ton of responsibilities that could vary significantly. Of course, it depends on how many and the age of each of the eldest siblings there are.
On the other hand, the oldest gets to do a bit more than the younger children like going to slumber parties or going over to Grandma’s alone for a week to help her out around the house. That’s usually the time Grandma spoils the oldest by sliding them some cash only for themselves, buying their fav out-to-eat meals the entire week, and/or taking them on a special trip or something.
The youngest child gets away with a lot such as not having to do house chores, getting to leave with the parent(s) majority of times when they go out to take care of business or whatnot, and getting most of the attention from everyone else in the family, including distant relatives. They also don’t get punished as much as the rest, especially not near as much as the oldest child.
On the other hand, being the youngest excludes them from doing many things older children are able to do. Therefore, it depends on the situation regarding which of the two is better, being the oldest or youngest child.
I’m right there with you, Cheryl! At 6 years old, I had 4 younger siblings; 3 sisters & 1 brother and learned how to change a baby’s diaper for the first time, too! Now, I must admit though, that there’s something about being able to claim & own the “oldest” title. I can remember those times of us children standing around either one person or a few people on different occasions and someone always seemed to ask, “Who’s the oldest?” The only thing that would come from my younger siblings would be a look my way that was filled with complete silence until I would speak up, “Me,” or “I am.” All I know is It felt & still feels good for some reason or another! LoL

Perfectly concluded!
I had 3 younger sisters by the time I was 8 and relate to much that you’ve said.
