OP thought she had finally found a manageable compromise with her MIL: weekly visits limited to two hours because her newborn is exclusively breastfed.
It wasn’t ideal, but at least OP could control when the visit ended.
Then MIL casually brought up sleepovers and immediately started preparing for one, even researching and buying a bassinet for her home.
OP never agreed to send her infant away overnight, especially at such a young age, and now wonders how to stop MIL from treating a possibility as if it were already a promise.
New mom is stunned when her MIL starts planning an infant sleepover despite never being asked
Few things make a new parent feel more vulnerable than realizing someone else has begun making plans for their baby without waiting for permission.
What looks small from the outside, a bassinet purchase, a comment about sleepovers, another weekly visit, can feel enormous when the parent is already adjusting to an entirely new life.
In this story, the mother’s frustration seems less about one piece of baby equipment and more about repeatedly feeling that her decisions are being treated as obstacles to work around.
The emotional conflict is especially interesting because both women may be acting from attachment, but expressing it in completely different ways.
The MIL appears excited about becoming an involved grandmother and may see overnight care as a milestone of closeness.
The mother, meanwhile, sees an 11-week-old infant who depends heavily on her and has no need for a recreational sleepover.
Each new purchase may therefore register not as generosity, but as pressure disguised as preparation.
There is another psychological angle worth considering.
The mother initially responded casually to the idea of a future sleepover, perhaps because saying “yeah sure cool” was easier in the moment than creating tension.
Her MIL may have interpreted politeness as genuine agreement.
That does not entitle the grandmother to determine when an overnight visit happens, but it shows how conflict avoidance can unintentionally create ambiguity.
The real problem emerged when a hypothetical “someday” rapidly became planning for “soon.”
That distinction fits this situation almost perfectly. The grandmother can be loving, enthusiastic, and genuinely well-intentioned while still overstepping.
Likewise, the mother does not need to prove that her MIL is incapable of caring for a baby before declining sleepovers.
Parental authority does not depend on winning an argument about breastfeeding, age, bassinets, or experience.
The most useful next step may therefore be simpler than debating every purchase: establish the rule first and let future decisions follow it.
Sleepovers can wait until the parents decide they benefit their child and feel comfortable with them.
A bassinet bought in anticipation does not create an obligation.
Grandparents can build extraordinary relationships through ordinary daytime moments, and perhaps the healthiest closeness begins when access to a child is understood as trust to nurture, not a milestone to claim.
See what others had to share with OP:
These commenters urged OP to reduce visits and stop encouraging MIL’s sleepover expectations
These commenters agreed OP needs to give a direct “no” instead of soft hints about boundaries
These commenters encouraged OP to become firmer and prioritize protecting the child over avoiding conflict
These commenters questioned why MIL wants unsupervised baby sleepovers so badly
OP’s MIL has apparently skipped several steps and gone straight from “maybe someday” to shopping for baby furniture.
A casual “sure, cool” about a future sleepover hardly sounds like a binding childcare agreement, especially when OP never actually agreed to a specific age or arrangement.
Do you think OP should clarify the boundary now before MIL buys an entire nursery, or let her learn that a bassinet doesn’t come with a reservation for the baby?
