Does anyone else have this problem?

I'm almost 18 weeks and this will be the first grandchild for my parents and the second for his. We are frantically trying to get some big projects done around the house and our parents, along with the siblings that have come to help, won't let me do anything! They treat me like I'm made of glass! I'm aware that I can't or shouldn't be doing certain things (heavy lifting, climbing ladders, etc) but I can do things like paint, cut boards, nail trim, etc but they won't let me anything but clean up. I even bought a respiration mask so that I could paint.

I guess I'm just asking, does anyone else have an issue with family treating them to delicately? Is it just with the first grandchild or does it continue?
