L.M.
My 3 yo son has his lovey he sleeps with and it's perfectly normal - healthy even (my daughter had a blanket for a long time too). I don't see any harm in introducing this to him, although it may take some time before he finds something he connects with. Maybe put several in his crib and see what sticks - at 1 yo he should be able to have some stuffed animals in his crib. One piece of advise though - once he has connected with something go buy another one as back up - I speak from nights of searching for "guy" only to find him 3 days later in a suitcase side pocket - apparently they were going on a trip.... *sigh*
