I'm the oldest.
I am really empathising with DS1 atm as DS2 grabs all his toys, enters his personal space (DS2 is learning to stand up and has a handy toddler-sized support - or so he thinks...) and basically gets to grips with "sharing" everything.
Would I feel more empathy for DS2 had I been the youngest, do you think? I mean, clearly I mediate and I make sure they take turns, etc - and I don't have a favourite - it's more about feeling more empathy for the big kid whose space has been invaded.
Am I alone in this? Do youngests feel more empathy for their youngest? Middle children feel more for their middle children?
