The birth of a baby is one of the happiest events in a person's life, if not the most. But a child is far from just adorable tiny fingers, plump cheeks and gurgling. This is a huge responsibility and a huge work for parents.
Especially for the newly-minted dad and mom it is not easy in the first months of a baby's life, because he constantly needs attention, including at night. Constantly you have to get up to the little one, then feed, then change the diaper, then something else. And in the morning the father goes to work, and the mother - to spin around the house and take care of the baby at the same time. Wake up the night. It is very difficult, and disputes begin as to who should go to the baby this time. Quarrels are generally not a good thing, and especially in such a difficult period. Of course, pillowcases for parents will not make this difficult work easier, but maybe at least they will prevent unnecessary quarrels. Or just serve as a good gift with humor for the young.
So, on the pillowcases there are inscriptions, on the one hand - "on duty", on the other - "off duty". Thus, in one light movement, parents change at the post, and when the crying of the baby wakes them up, sleepily remembering whose turn it is now is not necessary.
The main thing is that someone does not start cheating.
