Adoption regrets?

My mom is in her mid-fifties. She and I each had children young. I was sure hubby and I were supposed to have a big family. My mom thinks we're nuts for even considering starting all over. She has had a MARVELOUS life the last 16+years and we have enjoyed watching her do so. And there are aspects of it that are very appealing, especially less worry about money!Or imagine raising another set of kids....and with all the wonderful parts of parenting, these ones come with an extra big helping of challenge.We've chosen the latter (at least if things work out...). There certainly is nothing wrong with sipping wine on a mountain top inn in Colorado and biking to Florida though!If you truly "can't imagine life without her" then maybe she is supposed to stay. But if you think you may be able to live with "thankful she was part of your life," then maybe another family is supposed to be hers.
