Barbara-
I'm glad you are feeling better! Let Lynn assume the burden of dealing with all of this *stuff* - you and Lou are DONE raising kids

It will all work out - even if you and Lou *don't* jump to the rescue, you know! It is okay to say NO!
My brother and his wife just had their 4th child. My mom was over there 3 days in a row watching the older 3 (she was scheduled to be induced, then got *bumped* to the next day, GRRR) all day...she is turning 75 in a few weeks, and this stuff exhausts her! She is starting to have a few health problems (thyroid etc...) and can't really do it so often-she doesn't have the energy! My sister in law "doesn't do babysitters" - it's not a money thing either - so my parents feel obligated to babysit since they know there is no "backup" plan since they don't feel comfortable having anyone else watch their kids.
I told my mom she needs to tell them "NO" and they need to deal with it. It is not fair to burden grandparents in that way, and there should be no guilt feelings if you have to decline a request. No one can take advantage of you unless you let them....
I'm sure special arrangements can be made w/the college for a late start or whatever - but LET LYNN HANDLE IT! You and Louie need to focus on taking care of yourselves. I hope this doesn't sound harsh, Barbara, but I know all of the *stuff* tends to stress you out, and that is not a burden you should have to endure! This is the time in your life you have worked so hard for, and you need to be able to enjoy it!
Take care,
Mary
