How old is too old to adopt a newborn

Keep in mind that, adoption or not, people are starting to have children later and later. It really depends a lot on your health and how young you feel. I know some 43 year old who would definitely not want to have a newborn now, but if you feel you can, why not?In the mom club I belong to, I actually think I'm one of the youngest at 30 to have infant twins... quite sure a few are 40 or close. Dh is 45 and I still hope we'll be in a good situation to adopt again in a couple years (although I wish we could adopt a toddler or two then).Honestly I don't think the whole 'I'll be too old when they graduate college' is really a problem until you're 48 or something when you adopt... Plus I think it helps if they have siblings, and it's a bit less of an issue, as they'll always have each other whatever happens.
