I have a great support! My kids LOVE it (daughter is 3 and son is 1, haha) and my husband has bought me lots since I started (in August). My birthday, Christmas, and Valentine's, all I got was ponies! It's been great, but I will say, I'd like other things sometimes now, haha. But at least he knows what to get me now!
My parents are 'understanding' I suppose. They hate when I talk about it though, and go on about how I should get a job or something because I'm 'regressing'. Sigh. I thought they knew me better than that. When I get into something, I GET INTO something fully. Crazy, really. They dont' have any issues with me liking Mario or Zelda stuff... I spend more on those games/systems than I have on ponies.
And my husband collects Transformers and Star Wars... I've supplemented his collections since we've been married (ok... all he had/bought himself were the Star Wars books and his childhood transformers... all the rest came from me, haha)
