It's so lovely to read about someone who knows they definitely do want children.
While I am personally childfree (sterilised and everything), I believe all children should be 100% wanted and planned- not 'stressful accidents to work through' or 'well it was now or never' or 'I could take them or leave them but my partner wanted them.' (All things I have heard.)
So your post made me smile as it's such a refreshing thing to read and I hope you get the children and family you dream of. :)
