Don't feel guilty, like you said your SIL is probably looking forward to it

I know what you mean though. I feel guilty too. My mum and aunt have babysat occasionally when Charli has been sick etc and it means a 1 our trip for them to our place so it's probably more the distance and them going out of their way that makes me feel bad.

I've never ever asked a friend to babysit though. Although some have offered, I do feel super guilty about that. And we probably shouldn't feel guilty at all.
