AITA for telling my kids stepdad that our sitter doesn’t answer to him?
A divorced father shares childcare duties with his ex-wife for their two young sons, hiring a beloved sitter named Matt who works flexible hours between their homes. The ex-wife’s husband, Addison, often steps in to help with the kids, sometimes directing Matt to leave early or handle extra tasks like cooking or walking dogs.
Recently, Addison told Matt to go home so he could spend time with the boys, frustrating Matt who relies on those hours. The father confronted Addison, insisting that Matt answers only to him and the ex-wife, not the stepdad. He worries about losing Matt, a rare find, and resents paying for services that benefit Addison’s household.

‘AITA for telling my kids stepdad that our sitter doesn’t answer to him?’
The family relies on a flexible sitter to manage busy co-parenting schedules.

The stepdad frequently intervenes, which is starting to cause problems.



A recent incident led to a heated argument over Matt’s role.





This conflict revolves around unclear boundaries in a blended family, where the stepdad’s well-intentioned involvement clashes with the parents’ agreement on childcare. The father is right to protect Matt’s role and hours, as sitters are hard to find, and extra tasks like cooking or dog-walking aren’t part of the job description. Paying for childcare means expecting professional service, not free labor for household chores.
On the other side, the ex-wife and stepdad see Addison as part of the family unit, entitled to direct activities in his home. Since custody is 50/50 and costs are split, they argue Addison can decide how the time unfolds when the kids are there. However, this overlooks Matt’s perspective—he’s not a live-in helper but a paid professional with his own schedule and needs.
Ultimately, this highlights the need for co-parenting communication. All adults should agree on Matt’s responsibilities upfront, perhaps in writing, to avoid resentment. The father’s frustration is valid, but framing it as Addison needing to “f__k off” escalates tension. Prioritizing the kids means fostering cooperation, ensuring Matt feels respected, and recognizing that a loving stepdad benefits everyone.
