I'm planning to go back to work when my LO is 4.5 months. I have been exclusively breastfeeding and feeding on demand. I plan to pump every 3-4 hours at work. I just read in other threads that moms can maintain supply by doing night feedings. However, my husband is pushing for sleep training which means our baby would sleep through the night. The book he read advises to wean night feedings.
Has any moms here gone back to work and sleep trained? Does it affect supply? My LO currently goes to bed ~7pm, wakes up at 1:30 am for a feeding and sleeps again until ~6:30am. When awake, she feeds ~every 2 hours.
