A baby changes a relationship.
It does not arrive as neutral new joy.
It arrives with sleep loss, money, responsibility, physical recovery, less privacy and a permanent connection between two adults.
If the relationship is already unstable, parenthood usually adds pressure before it adds solutions.
That is why "maybe a baby will bring us closer" deserves careful examination.
A child should be wanted for themselves
Ask each person separately:
"If our relationship stayed exactly as it is, would I still want to become a parent with this person?"
That question matters.
Wanting a baby because you both want to raise a child is different from wanting a baby because the relationship feels empty, uncertain or fragile.
