yes he is still a puppy it is normal he is still looking for his mom’s tit. just but him a kong for puppies or some other stuff from kong for puppies that will help stop ur bullie from sucking on everything,plus you can get a toy animal a little bigger then him so when he naps or something you can give it to him,maybe he just feels lonely?? just give him all your love and he’ll give it back to you also. good luck
