I’m going out on a limb by saying this, but I think that in my situation, I’ve been very fortunate to have had a lot of practice in raising children, without having given birth to one of my own. Sometimes I feel like that gives me a bit of a leg up on the whole parenting process, when compared to other first time parents. (That’s probably poorly worded, I’m not pregnant.. just for the sake of preventing confusion.) Having said that, I think one more child would be enough. Limitless funds, or otherwise. Three children sounds like plenty, for me.
