About six paragraphs from the end there is reference to older ones entertaining/caring for younger ones.
I do remember some specific chores involving caring for and teaching youngers, but overall they were so much fun ! I remember lots of time around the baby's bed laughing, " peekaboo ", etc.
So, were your younger siblings work or fun ?
And for the younger siblings, were your older ones helpful, surrogate parents, playmates, or ....??
(Also somewhat elliptically enfolds the question of " village " or " team " effects on younger children compared to older)
