Daughter will be 1 in 2 weeks.

Our daughter turns 1 in 2 weeks and my husband’s birthday is a week after, I was wanting to plan a night with him for his birthday just the two of us. It has been a year of just being me and him alone. Our daughter is breastfed and will not take a bottle!! She does however drink water from a bottle like we drink from or from a hard straw. I have not been away from her in almost a year. No sleep in that long and no alone time with my husband in the long. Would it be bad to let my mom keep her for one night so my husband and I can enjoy a night alone that is long needed in a year? She does night comfort nurse and I’m really wanting to break her of that! Would it be wrong for me to let her stay at my moms for one night?
