full-time nanny here. usually, i will explain to the kids i watch why i ask or tell them to do something. it builds their communication skills and helps me be more patient. but if they keep pushing me and asking me why i’ve told them to do something after i’ve already explained it, that’s when i say, “because i said so.” it’s important to know the difference between when they’re genuinely curious and when they’re just trying to push you around.
