Re: Pumping frequency?
First off - way to go for EP'ing this long. I basically EP'd with my oldest, she never caught on to nursing either and I would nurse her for one meal per day (right after work) so I know how much work it is!!
If it were me I would give it a try and cut back to pumping every 4-5 hours, but I would also pick up some fenugreek so that your supply doesn't slip TOO much. And if it does and you aren't able to pump what he is taking in each day you may have to go back to every 3. But keep in mind that your body eventually stops responding as well to the pump.
Changing the membranes is an excellent suggestion too! So is switching up the strengths during your session.
