How much do you give to your MIL for allowance to take care of your child?

The amount really varies, depending on your family income. Good to check usually how much your hubby gives her for allowance. Then you can decide the top up amount. Some of my mummy friends give as little as $100. The max I have heard is $1,000 (with every Sunday off - and not including diapers and other supplies). For us, when my mum helped we "paid" her $700 for helping out.
