Your husband needs to recognize that your full-time job is what financially supports the household. When your son fell sick before your crucial meeting, it was reasonable to ask him to stay home since his night out with friends was non-essential. A major work commitment that could affect your family’s stability should naturally take priority over a casual outing.
It also seems your husband may have misrepresented the situation to his mother, leading her to believe you neglected your son for your career. To protect yourself and prevent false narratives from spreading, it’s important to calmly explain the full context to your mother-in-law — that you had a critical work obligation and your husband was initially responsible for caring for your child during that time.
Your husband’s defensiveness may stem from deeper insecurities about being a stay-at-home dad and societal judgments around traditional gender roles. Feeling inadequate, he may have reframed the situation as you being “too career-focused” to preserve his pride. But this doesn’t make you a bad mother — it makes you a responsible working parent making necessary choices under pressure.
Moving forward, you both must set clear expectations for future emergencies. Agree in advance who takes over childcare when conflicts arise, or arrange trusted backup support like a vetted babysitter or family member. With clarity, communication, and mutual respect, future misunderstandings — and emotional fallout — can be avoided.
