Sibling dynamics, what are your experiences?

[mswhereami]

I have a girl and a boy and we are planning a third but I worry I may upset the balance a bit.

I am from a family with 4 girls and 1 boy and there is a lot of love between us.
DH is from a family of 6 boys and 1 girl, they all get on but also fall out a lot.

Anyone from a GBB or GBG family or have those combination of children? Did it change the dynamics at all? Can you have two boys that won't just fall out all the time (read on a previous mumsnet thread).

I know a lot is down to parenting and personality, my current two are very sweet and caring but would say DS was born a wild child and needs taming from time to time, not sure if I can handle two of him 😅.

Please can I also not have answers like 'this is mumsnet we don't know what your babies will be like,' this is a forum for parents and I would love to read through your anecdotes 😊.

I'm one of 4 GBGB and me and my 2 brothers were all extremely close when young, I was very much a wild child. Now we're all close but I'm still closer to my brothers, my sister is now close to my older brother.
My children GGBB my first boy was always very sensitive. You can't say how wild a child will be. My youngest is 15 but other 3 adults. GB closest and same again although all get on.

Just to add my brothers get on as so my 2 boys.
