I Spoiled the Milk

Oh, No! I spoiled my son's milk! I was off to bed like dead and even my alarm I never heard. Before going to bed I already set my alarm to wake me up few hours after because I already prepared my son's milk. At 12 midnight is his drinking schedule for the first bottle of milk, but what happened was I surpassed the time frame which the prepared milk is good and fresh. So what's my choice? Toss the milk away. Oh, no! It's another waste. I think I need an alarm that is very loud and clear that even my neighbors can hear.
