I love Alexanders name, I would have been devastated if H (tried to) vetoed it, I honestly can't beleive every little boy isn't called it. I do wish I was braver and pushed the shortening of Xander more than Alex though.
When it's just me and him I often call him Xander in the hope that he'll prefer it at some point. He's not even 9 months, so it's a long game I'm playing! 
We decided on a girls and boys name before we found out the sex at the 20w scan. I relented to H's choice for a girl - Katherine/Katie/Kate/Kitty. I'd been trying for ages to think of a name like Kate, or more in 30 years time would be today's Kate IYSWIM, but couldn't think of one (probably due to the lack of a time travelling device) so agreed to it when it was the name he professed to love as much as I do Alexander, but was secretly thinking that I'll have 20 weeks to find a name I love and convince H if we find out it is a girl, and this way I get Alexander if it is a boy!
I'm already sowing the seed for Nathaniel for a second boy, which is the only boys name I like anywhere near as much as A. There are still no girls names that I love, and I think this is the main reason I'd love another boy.
