Towards the end of my pregnancy with DS (we'd been married for 3 years then) I went out and bought myself one. I got it designed and made specially with 5 diamonds (in a row) to match the two either side of my ruby engagement ring. I tell everyone (except you ladies here right now of course )that DH bought it for me to celebrate the birth of DS. I did tell DH that I was going to go and do it, and he didn't protest too much, so that's as good as buying it for me I reckon.
