You have equal rights to the child so she can call the cops all she wants. In fact, you should go pick up your child so that it's on record that your husband told her to call the police if you came to get your child, knowing that he was just doing it to try and scare/control you. It'll show he's playing dirty.
As far as the emergency custody, the longer you wait to file, the less it's going to seem like you're genuinely concerned for their safety.
