DH has mentioned a few times that DD calls our nanny "mummy" when I'm not around, and our nanny doesn't correct her. DD is almost 2, and speech has come on leaps and bounds in the last few months. Our nanny's name does end in "-mmy", so it might be a pronounciation issue, but it has sort of upset me.
What is the best way of raising this with the nanny without sounding precious? Is it an issue? I'm feeling a bit upset about it, but I think this is compounded by being back at work after 2 fab weeks with DD and getting a text today from our nanny telling me what a lovely day she is having with DD.
