Is it normal for a much younger sibling to boss you around ?

Kids, especially younger kids are spoiled and bossy. It's normal, although if not checked, it can move on into adulthood.

They'll stop bossing if you stop listening.

When I was a kid / teen my 3 younger siblings would always boss me around.

I was a preemie baby and because of that was small for my age and hit puberty extremely late. I was a nightly bedwetter and daytime pants wetter so my parents kept me in diapers fulltime. Both mom and dad said only babies wear diapers and there for since my younger siblings were all dry and out of diapers for years, were considered to be older then me and given the official position of being the big brothers and big sister to me. They were all taught to change my diapers (babies can't change themselves I was told) , to spank me , put me to bed and whatever else they decided was in the best interest for the "baby".

so for me it was normal to be bossed around by my younger siblings. Each situation is different.

My sister is 4 and I'm 22 and she bosses me around. I also have a 8 year old brother, who also bosses me around.

I use to boss around my younger siblings they never ordered me.

Yes, my 22 yo sister acts like shes my second mother and I'm some immature fuckwit, which, i kinda am but still, there's the principle of the matter. I'm 26 btw.

Yes!! My brother is 2 years younger but since he's strong and tall he acts like the boss.
