Everyone's Input Please

Aspen's mother and I share joint custody. I have my daughter half the week, she has her half the week. Is it unreasonable for me to ask/expect that if she is picking up Aspen early from school or keeping her out of school for any reason on any given day that I be notified by her in advance?

Likewise, is it a fair request that if she takes Aspen out of state for a day or two (during her time with her) for whatever reason, that I be notified in advance of where theyre going and for how long?

edit: thanks for all the input folks. it will be put in writing and signed by both parties that this sort of info will be shared from now on (the custody settlement was not that specific).
