My sister's father-in-law always provides a "baby moon" for her and my brother-in-law before the birth of their babies. I've always thought that was a great idea--a chance for mom and dad to get away and have one-on-one time before adding another child to the family.
However, I now have another suggestion. My definition of a baby moon is to have your older children taken for a couple/few days so you are left with only your youngest...your baby. It has been incredible having these past few days with Avery. And these will likely be our only days just us before she is no longer our baby. She has loved it, Braden has loved it, I have loved it. It has been so rewarding.
(I wouldn't, however, recommend coinciding this baby moon with packing to move. It definitely cuts into the "quality" time.)
