It is not easy for your children’s carer, be they partner or ex-partner, at home. They are left with a pretty significant burden of sole responsibility for the children. The sole parent feels the pressure of responsibility as they are not able to relax and switch off as easily.
For some mothers, the extended family are able to give relief in the pressure of being the sole carer. If not, perhaps you can pay for a baby sitter or carer to give your partner or ex-partner some relief.
