debbie, my nephew is 16 months and still has three bottles a day. i dont think there is anything wrong with it from a comfort point of view, if they are not putting on too much weight from the solids and the milk, then what is the harm, all babies have their security blankets, jackson's is his little stuffed pup he sleeps with and if he wants to do that until he is a teenager then so be it (i am slightly exaggerating there!)
