DH and I really want to go away for my milestone birthday in December.... youngest dd will be 10 months by then. We have found a great deal for 3 nights away but need to book now or could go.up massively because of the time of year ... How old is acceptable to leave dc for 3 nights with grandparents. Is dd to young... 3 nights to long or am I worrying about nothing. What we're your experiences?
