When my daughter was a baby, the mattress protectors came in handy when she would throw up or a bottle would spill. Obviously, the mattress protector is still around and being used in our household. Of course, they aren’t just used for babies and toddlers. They’re ideal for older children who still battle bedwetting and older adults who may not be able to make it out of bed in time to make a trip to the bathroom. A lot of nursing homes will use them; hospitals take advantage of them too. Any time you want to protect your mattress from being soiled from anything, using mattress protectors is the key.
My husband and I have one on our bed as well.
