I always make sure to hand upset babies straight back the moment they show signs of not wanting to be with me.
really..?

See I always feel guilty if I do that... kinda like saying to the parent .... "oh, I'm happy to have your child when they are being nice... but if they are crying, then you can have them..." I try to comfort the baby, but if it's becoming clear that they really need mum or dad then I'll hand it over.... but I want to be helpful to the parent, and not 'run to mummy' anytime there's a problem....

I think I probably wouldn't if it was a stranger.... mostly because they don't know me, and I could be some crazy for all they know but I'd accept help from others for 'non-baby' tasks... I think....

we will see what happens in reality if I ever have a baby...

I'd like to think I would help people - but I think realistically... I probably wouldn't
