We just took them away and it worked great for us, but my boys were older, my 1st was right around a year and my 2nd was almost 2yrs. So they def understood, your a big boy and you don't need it anymore. I don't knw about at that age though, I don't mind them having them until they are a bit older, my almost 16mo old has his and we probably won't take it away for awhile still
