Good luck with your tough decision. The only advice I would throw in there is to be careful of your budget. It wouldn't be fair to any of the little one's if one came up sick and you wouldn't be able to cover the expenses. The other thought I had was that they both need special attention and are deserving of it. If you had three little one's, would you really be able to devote enough attention to all three? How about going for walks? Would you take three? Just thought I'd throw some of these ideas at you as food for thought.
