Lo is coming 5months. Still need to be rocked to sleep. Should i start sleep training ? or he will slowly outgrow it ?

yes slowly you can train. i pat my son to sleep till he is 7th mths old. me and my hubby decided that we should leave him inside his cot and dim the lights and leave the room. we peeped in and check him from the door every 5mins. slowly he will sleep on his own without me patting him to sleep. all babies are different. so need to trial and error.
