What is the way to let your 5 month old baby sleep through the night

Do you mean drop the night feedings? We gradually delayed my baby’s midnight feeding when she’s about 2.5months old. Her last feeding is usually at about 11pm. Her subsequent feeding is 1am, we dragged till 2am, then 3am and etc. Now she sleeps till 7am or even 8am. And we give her the pacifier too.
