Not me but my cousin.
She's just had her first baby and is due to go back to work in a few weeks, however she's now decided she wants to be a SAHM and have a couple more kids.
Her DH works full time (as did she) and they earn approximately the same, for arguments sake say 40k each. Before having the baby the arrangement was my cousin would go back to work full time and her MIL and mum would split childcare.
Her DH is not particularly happy and wants her to go back to work so they can have the bigger house/car they'd always planned.
So who is BU?
