My mom gave my little man a new outfit recently and it was so cute and he only wore it once and I thought he could wear it today since its cold out and its a warm outfit. Well I go to put it on him and I can't find the pants. They just disappeared! I remember washing them and putting them in his room but they are no where to be found now! Isn't that weird? I have no idea what could have happened. I looked in his sisters clothes and they aren't there either. It's going to bother me but they are just pants and he has a lot of other pants. 😠😔😬😁
