Re: sudden drop
I'm sorry this has been such a struggle for you!
The best things you can do when you're having supply issues are to pump more often and to use a better pump.
You want to aim to pump every 2-3 hours during the day and every 3-4 at night, maybe allowing yourself one 5 hour stretch of sleep. Pumping every 4 hours is generally not enough to maintain milk supply when mom is exclusively pumping.
The Pump in Style is a good pump but there are better machines out there (think hospital-grade rentals). The manual pump... Well, frankly that is just not an appropriate tool for a mom who is relying on pumping to maintain supply. It won't give you the stimulation or milk removal you need.
So, to reiterate: pump more often and get yourself a better pump!
