We are a family of four, two adults and a 14 and 11 year old . Since the lock down our grocery and household bills have increased to approx £400 a month. I have tried to explain to my hubby that the kids are not eating in school so it’s 3 meals , snacks no restaurants or takeaways and he thinks I’m being extravagant. I think this is perfectly reasonable as this includes all food plus cleaning products etc . Is this reasonable or am I being hopelessly extravagant?
