Hello mother , Try to reducing evening naps and overall sleep duration of day time . Slowly child will get habit of sleeping whole night or will sleep a immediately after having milk. Feed him properly befor sleep and keep milk ready for night so that you can immediately warm and give to child and don’t switch on bright lights or baby making child sleep later will be difficult .

Feed the child adequately before sleep. So he can sleep well. Hungry child often gets up. Give him semisolid diet.
