No, it's not okay. Spanking a baby is not a proper form of discipline at all. Babies are too young to understand such actions as discipline, and it can cause harm to them both physically and psychologically.
The husband and wife are key. The husband is the one doing the delivering. There might also be a midwife character who was supposed to be there but got held up, so the husband has no choice but to step in. And of course, the new - born baby is also an important character in the end.
In this kind of fanfiction, the plot could involve the husband having studied some basic medical knowledge before. So when the unexpected situation of delivering the baby at home arises, he uses that knowledge. He may also have some superhuman determination to keep his wife and the new - born safe, adding a touch of heroism to the story.
An 'adult baby husband story' could be about a man who, due to some past traumas or over - protective parenting, has the mentality of a child in his relationships. For example, he might get extremely jealous easily like a baby does when it doesn't get enough attention. His partner then has to find ways to communicate with him on his level and help him grow emotionally.
In some cases, it could be due to a lack of self - confidence. If a husband has low self - esteem, he might act like an adult baby. He may rely on his partner for validation and support in every little thing, just like a baby depends on its parents. This can be seen in many 'adult baby husband stories' where the partner has to constantly boost his confidence.
Once upon a time, there was a couple. One day, through some strange magic, the husband was turned into a baby girl. His wife was shocked at first but then decided to take care of him. She dressed him in cute baby clothes and fed him with a bottle. It was a really strange situation but also full of love as she cared for him as if he was their real baby.
Let's avoid the 'adult baby' idea which might be off - putting. Consider this story instead. A husband was really into DIY projects. One day, he decided to renovate their bedroom for his wife as a surprise. He spent weeks planning and working on it. When he finally showed it to his wife, she was overjoyed at how much effort he had put in to make their living space more beautiful.
It can also lead to an unequal power balance in the relationship. If a husband behaves like an 'adult baby', the wife may end up taking on excessive caregiving roles, which can cause stress and resentment. This is not conducive to a harmonious and long - lasting relationship. Additionally, it may be a sign of underlying psychological issues that need to be addressed rather than being normalized.
Sometimes it might be a result of a psychological experiment within a story. A psychologist or a curious family member wants to understand how a grown man would react if put in the situation of a baby. So, they force the husband to be the new baby to observe his behavior, emotions, and how he adapts to being completely dependent on others for a while.
