We are going on honeymoon and DD aged 3.3 yrs is staying with my mum for 11 nights. My mum has looked after DD before (occasionally) for 24 - 36 hours and I do usually speak to DD on phone about 3 times while away (because I miss her). This time we will be in Cuba so 5 hrs behind and expensive to call. Should I call DD regularly or will it upset her? Anyone have any experience/ views?
