#asktheexperts Hello doctor, my son is 18months old, for past two months he's often waking up in night to breastfeed, if not he's screaming and not getting console unless I breastfeed.. previously he was thumb sucking he left that habit and started to breastfeed whenever he wakes up at night. Normally without breastfeeding he's not sleeping by himself. My question is how to make him sleep by himself without breastfeeding, and how to make him sleep without waking up in night?
