V.N.
I pumped after feeding my son at 7:30 am, then left for work. I only pumped one time at 2:00. I then fed my son at 7:30-8 pm when I got home or on the way if I was running late. I worked two or three consecutive days with one or two days off in between. When I was home I would breast feed exclusively and pumped afterwards occasionally to get more milk.
I did not notice any decline in milk. My son weaned himself at 6 months from breast feeding. He simply refused. I tried everything including a lactation consultant. I was able to pump until 10 -11 months and then my supply declined rapidly. So I thought luckily I had stored enough milk to get him to one year. Then one day around 11 months he refused to eat or drink anything with breast milk in it. I tried for a long time and gave up throwing away a ton of milk :(
It was not easy but for me it was worth it.
