Mother's Day and food go hand-in-hand. Blame the tradition of breakfast in bed (an activity that, more often that not, just gives the gift of a dirty kitchen). Come April 14, your celebration will likely involve something edible.
Instead of going with waffles consumed while lying down, why not go with a food gift that will last well after Mother's Day is over for the year? After all, with all they've done, from bandaging booboos to explaining how tax returns works, one day is hardly enough.
