When my boy was little, he would say "valentime" instead of "valentine." Which really makes sense, with Valentine's Day coming right after Christmas time. I never corrected him for this, or for any of the words he mispronounced, because I found it so cute. Despite my best efforts, he eventually learned the proper way to say Valentine, as well as "lellow," "pillowdo" and every other word.
Anyway, I wish you and yours a Happy Valentime's Day.
