Hubby got discounted airline tix to Europe & said I should go. We have 4yr-old child. Should I go for a week?

Would I be a bad mother if I go to Europe for a week? I will probably go with a friend or my sibling. I asked my husband if he's sure it's ok, and he insists it will be fine. (And no, I'm not concerned about him having ulterior motives, in case people may wonder about that). ;) What do you mothers out there think? Please, only serious answers to this question. Thanks. :)
