my milk supply also dropped but my baby is eating cereal to replace one meal, so i still feed him all breastmilk
my schedule is like this
1. pump in the morning on one breast (0630) and feed baby on another breast before work (0700)
2. bottlefeed baby breastmilk (1100)
3. pump both sides during lunch time (1300)
4. bottlefeed baby breastmilk (1430)
5. cereal+banana puree (1830) + on breast
6. on breast (2130)
if i have time, i might pump more but at least pump according to the above schedule
it's very tiring and hope i could persist, my son is 7 months old today and i hope i could continue until 1 year old
