Donât ditch your childâs booster seat too soon. In the last 20 years, America has seen a 71 percent drop in infant fatality rates from vehicle crashes, thanks to the proper use of car seats. For children ages 5 to 12, vehicle crashes remain the number one cause of death in California, according to a California Department of Public Health study.
A buttercream frosting made with water instead of milk will last for a couple of days. I imagine the canned stuff you can buy in a grocery store will last longer due to preservatives. As an alternative you could just make whatever frosting you felt like, and keep it refrigerated until you needed to use it.
Refrigeration generally dries out a cake, so unless the icing requires refrigeration, I don't recommend storing a buttercream covered cake in the fridge to keep it fresh. Cream cheese icing, whipped cream, and certain fillings (especially fresh fruit) SHOULD be refrigerated so they won't spoil.
