I lay myself before the mumsnet jury. Please be gentle.
On Tuesday 4 chocolate cookies were delivered as part of the grocery shop. My 3dc didn't eat them because they were too full after I insisted they eat fruit first (Good mum emoticon). Now they've gone to bed and I've remembered them. The packet says best before 23rd April. So if they eat them tomorrow strictly speaking that wouldn't be before the 23rd.
So my question is what wound you do? Do I save them one each and risk them having the experience of eating stale cookies. Or do I eat them all myself and hide the evidence?
