Thank you so far ladies. Lynnie, I will inform her that I'm available for as much as she/they want and that we'll follow their rules for their son. She knows I am currently a L/D nurse (and have been for 8 years).
Coopah, thanks for your advice of letting her take the lead and tell me what she'd/they'd prefer I do. She/they are the decision makers.
Jan in VA, when the time is right, I'll let her/them know I've signed up for a grandparents class. It's a 2 hour class. I am certified due to my job, in newborn and infant CPR.
Jingle, I hope to hold him as much as possible!
Maryb119, I like your grandparent description and rule of "Ask the parents first and just love the baby."
Quiltingcandy, thanks for your advice of cooking, cleaning, laundry and tidying up and your example of good and bad assistants. We truly remember those who helped and those who hindered.
