I unfortunately have both spider veins and varicose veins and I've never even had children. My mom had them so bad that she had to have some of hers surgically removed because her legs would get so swollen and hurt her so bad. I now hate wearing shorts in public because my legs make me look even older than I am. Luckily my legs don't swell or throb like my mom's did.

Here's a link about a cream for spider veins: http://www.skinenergizer.com/Spider-Veins-s/235.htm. I've never tried anything like this so I don't know how well it'll work. Good luck.
