How often should a newborn breastfeed every 24 hours to establish mom’s milk supply? The answer is (b) 8-12 times per 24 hours. It is important for a newborn baby to breastfeed at least 8-12 times or for mom to pump 8-12 times every 24 hours to increase mom’s milk supply, especially in the first few weeks after delivery. The more stimulation mom receives from frequent breastfeeding or pumping from day one after delivery, the quicker her body responds and begins to produce more breast milk. If baby doesn’t want to nurse, placing baby skin to skin is just as beneficial as stimulation for milk production. Momma, you can do this! Keep calm and breastfeed on!
