I have noticed this a few times. The partner is right there, sometimes even at home, but instead of expecting him to look after his own child, the childcare gets arranged with the DM or MIL.
It ends up being this system where the responsibility just shifts from one woman to another. The dad seems to get a free pass while the DM or MIL are expected to pick things up, often without much question.
I understand there can be practical reasons like work or routines. But I am talking about situations where the partner could do it and just does not. The assumption still seems to be find another woman rather than expect the father to parent.
Even when he does step up, it often still circles back to another woman. He will take the child round to his mum’s and expect her to take over, so it is still not really him doing the parenting, just delegating it.
Sometimes the partner might be a bit hopeless. But does that mean he just gets to opt out completely while other women step in. It feels like this just reinforces the same cycle. If he is never expected to do it, why would he ever step up?
I am not saying this is true in EVERY CASE.
