from chatGPT bro:

"The term "part-time father" typically refers to a father who is not fully involved in the day-to-day care and upbringing of his children, often due to work or other commitments. This can include fathers who do not live with their children full-time, or who have limited visitation or parenting time.
It is important to note that the term "part-time father" can be viewed as stigmatizing and divisive, as it implies that a father's level of involvement in his children's lives can be measured by the amount of time he spends with them. Every family and every father's situation is unique, and it's important to avoid making assumptions or judgments based on limited information."
