My son is 17 and starting university next week. My last child benefit payment is on Monday. It is only showing in my account as one weeks payment of £25.60. My last payment was on 19th August. I thought Child benefit was paid in arrears and given that I was entitled up until the end of August and 19th until the 31st is more than a week, should this last payment not be for more than this? I know it's only a matter of a few days but we are very much struggling to keep up with bills at the moment and falling into debt so every little bit helps.
