Chickenpox I actually wanted DD to catch, so no, I didn't worry about that one. Measles, Mumps, and Rubella, I didn't worry about much either. I figured she was still bf and they're not really so easy to catch it seems. I worry about it with DS and rotavirus though. Many mobile babies used to catch it from one another I'm sure, but their parents generally noticed when they were sick with it and avoided others; but with the vax, their parents probably shrug it off in terms of being contagious and the babes are so much younger than they'd prob have to be to have it naturally. I don't share rattles/toys between ds and other babies; I keep our own in my bag and give him those. When he's big enough to toddle over to the box at playgroup himself, I figure his immune system will also be strong enough!
Happy with my DH, 2 kids, dog, fish, and frogs
