You could ask him not to call while she's playing but promise to call just before lunch or before dinner and report to him how she's feeling, what she's having to eat, who she's playing with. It keeps the NCP feeling connected. It rips them apart when they're apart for so much and I can certainly understand why he finally decided to just start calling. And a bedtime call is absolutely appropraite for the same reasons. Just a little "I love you", or "good night, I'm thinking about you", or "make sure you say your prayers"... whatever is the bedtime routine from the NCP is worth a thousand words. Consider finding a way to make it a short call and part of her bedtime routine.
