mehimthem - the idea of 8 people in one house when there's a new baby is ridiculous in my opinion. The new baby and its immediate family need private time to bond - seems to me that everybody was a bit overly-sensitive, not surprisingly and your leaving must have been interpreted as your going off in a huff for whatever reason. I have my biological daughter within a mile of me, I was present at the birth (at home) of both my grandchildren. The other grandma was also present at the first birth but not the second as they live three hours' drive away. I also have a step-daughter who lives four hours' drive away from us and they don't have the accommodation to put us up so the relationship continues with us visiting and checking into a local b+b. It's expensive of course but there's no option. So, as others have said, why don't you visit but don't be on top of them by staying there, it's all too full-on, give them their privacy, and they'll welcome you more. I know there's a cost involved so that will determine how many visits you can make.
To go through chemo therapy or choose not to?
