Whenever I ask my nanny to enforce some boundaries with my toddler (eg. Eat lunch then go for a nap as opposed to skip lunch, skip nap and just play / put a hat on when it's freezing cold outside / come back from the playground at a certain time for lunch and nap), she often doesn't do it and responds with "I suggested it but your daughter didn't want to". In the rare case that she does enforce some boundaries it's "mummy said you need to leave the playground now" as opposed to just "it's time to go home" or "mummy said you need to wear a hat" as opposed to "it's cold outside, you need to be wearing a hat". So instead of presenting a united front Mummy is always bad cop.
I've spoken to her about it and her reasoning is always "I just don't want to upset her". Essentially there are no rules when my daughter is with her nanny. What more can I do?
