So how old is your bairn now, Flint? Couldn't you just put her in a safe place where she could watch you work out and you could watch her -in an exersaucer or something?
Beest and I exercise/work out seperately, but if his mom's over from the UK we go together and leave her in charge -it is more fun to do it together (
)
Really, though, don't stress too much about it. Just check the place out first, your gut feelings will guide you. It's pretty rare for nasty things which could have been prevented to happen, obviously you should make sure that the carers are trained in child cpr etc, but remember that knowing what you should do does not guarantee you will remember and do it when it matters, so your gut feeling about whether the person is competant is at least as important as the framed pieces of paper on their wall.
