Lots of people make sacrifices to pay childcare.
Life changes when you have children.
Her well paid mother can't be imposed uoon, but a 63 yearold can give up a shop job and work weekends to provide THEM free childcare?
They clearly can't afford a child.
So no holidays, new clothes, nights out, weekends away?
Or did they expect to maintain their lifestyle at the expense of your life, income and health?
OP, I hope you realise what an awful excuse of a man your son is and the horror he married.
It indeed takes some tale to shock on MN, but yours is shocking.
Watch carefully their expenditure going forward, because clearly they both must be on the breadline🙄.
Where are HER parents in this?
No help?, no monetary help?
All down to you?
You need to reiterate to your son clearly that you are very upset to be spoken to with disrespect.
Is this really how you reared him to treat you?
I would put him in his place so he doesn't ever forget again.
As for her?
She is the absolute dregs of society, which also says a lot for your sons judgement.
You sound like such a kind, loving, generous woman, utterly disrespected and taken advantage of.
You need to show them they made a BIG mistake thinking you would accept this.
You should not do any days.
You have other grandchildren to focus on.
I would not allow those to blackmail you.
They are an absolute disgrace.
Stay strong
