hello, my 15 month old son won't stop breastfeeding. I am slowly trying to stop feeding him except at night. However he starts crying extensively and doesn't stop unless I feed him He only want's to suckle to put himself to sleep. He has become used to thos way of sleeping and does not sleep in any other way... tried to rock him, cradle him, singing him songs....but nothing is helping.... please advise what shall I do .. even during daytime he will sleep while feeding.....and not by any other method
