I checked my toddlers ipad browsing history and saw 100 of pages of porn! The only person who has access to it is my maid - what should I do?

Oh no! That's awkward. I think you should definitely confront her. But also keep an open mind that other people may have had access to the iPad. Be firm but still polite in telling her that it will not be tolerated. If she seems defensive or unwilling to change her ways, let her go. I personally wouldn't feel comfortable having someone so careless around my kid. Sure, she's human and she has the right to check sites she wants. But she should do that on her own time and using her own gadgets.
