Scrunchie Well done on the TTC malarky. That's going some!
On the age gap convo. My parents had 5 children in 9 years, with 16 months between my sis and my eldest brother and then approx 2 years between each of the rest of us (i'm number 4).
We all get on and if any of us needed anything/help/support from any one of us we would do our best to help each other but I would say there has always been tension between my sis and my eldest brother.
Our relationships have changed over the years. When I was little I was closest to my little brother (2 years between us) but then we grew apart when I went to uni, I would now say our relationship is better and like we were when we were younger (now that he is no longer with is ex of 10 years and now with a friend/ex housemate of mine (they got together after my wedding!!)).
My sis and I have never been that close (7 years between us), we tried when we lived near each other when I was at Uni but I would say we talk more now as we both told each other that we are TTC. I think this has helped us support each other.
I have a good relationship with my eldest brother (5 years between us, I'm god mother to his daughter) and even went on holidays with him just the two of us.
I would like a better relationship with my middle brother (2.5 years between us) and am working on that this year..
