When I went back to work after maternity leave, i was still feeding and/or punping milk every four hours. My daily schedule will be to have the last nursing feed before work abt 7am, pump at work at 11am and 3pm. Will nurse baby again first thing after work at 7pm and 10pm. The 7am, 7pm and 10pm feeds are done concurrently with pumping milk to store. This continued till baby turned 1 when I reduced pumping sessions to only once during work hours. And when baby turned 18 months, went whole day at work without pumping. Only direct feed when baby around. No more pumping milk to store. Now “baby” is turning 3 next month and I am still breastfeeding her (direct latch only) in the morning before work at at night before bedtime.
Plan to breastfeed your baby in the morning before you go to work, then pump every 3 to 4 hours during the day (depending, of course, on your baby's frequency at home). That means that if you're away from your baby for 10 hours during the day, for instance, you'll be pumping at least 3 times at work.
