Good for you! It is never too late. Congratulate her on the realization she has come across personally. Does she read these forums with you?I finally convinced my wife that now is the time to build up our supply. With everyhting going on in the world she agreed and we have been buying extra every week.
Like it was mentioned earlier, having 3 kids makes it more complex.
The other items that we are loading up on are personal care items like soap, hand sanitizer, and OTC medicines.
