Well I can give the point of view from the child! lol

I have 6 brothers and sisters (3 of each) and my mum was pregnant with me (im the youngest) when my sister was pregnant with her first LOL

There is 21 years between my eldest sibling and I and 10 years between me and the 2nd youngest and while its extreme gaps, I will never have kids that far apart.

While I do get along with them all now when I was younger I wished I had younger brothers and sisters to interact with, That said they came in handy in my teens for lifts etc haha

I have a neice the same age as me, who was more like my sister...

Im not leaving more than 4 years at the VERY max
