Different babies are going to react differently, ask the parent/family what their child likes. I'd ask before I set up anything if it was OK - if you're in someone's home then you have to be respectful and be able to deal effectively with whatever is going on in their home while you're there.
My field is in child development w/specialization in birth to three and I've seen baby photography tutorials etc. that don't necessarily demonstrate appropriate techniques to use with a newborn (that might be OK with an older baby). Just because someone is doing baby photography that doesn't mean they have any particular expertise - just about anybody can post an article or video online.
If you are conducting a session, that puts you in the position of being responsible or liable for anything you do with someone else's child.
