Labbit,
Yes, especially when return back to office, baby is not with you, supply sure drop.And when you are stressed it is worst, even with a full breast the milk just can't let down. So you must be relaxed and at ease to stimulate the let down.Or bring a baby towel which has the baby smell to help.
I tried to help many friends on bfeed. Some latched on successfully, but there are some gave up.Then when their child falls sick, they have a hard time and regret didn't bfeed their babies.
There are ways to keep supply up or maintain.One way is to pump more frequent, or another way is to take supplement like fenugreek, brewer's yeast and some other herbs.But once back home, try to latch bb on directly so there is a direct stimulation from the baby.
During confinement, try to take more fluid as b milk is also a fluid. If not enough fluid intake supply also won't inc much.
Fluid does not mean plain water.We chinese esp old folks will say can't drink water. But you can drink plentiful of red date tea, soup, milk, etc.
Imptly is fluid, cos during confinement, our body also looses alot of water.
