When a baby arrives, it's a big change for everyone, including men. Suddenly, there's a huge responsibility to provide and protect. Some men "switch up" as they adjust to this new reality. They may become more focused on their career or withdraw from social circles to prioritize their family. Emotionally, becoming a father can be overwhelming, leading to shifts in behavior. Societal expectations of masculinity also play a role, challenging traditional ideals. Overall, "switching up" when a baby arrives is a complex process of adaptation and growth for men.
