Re: Urgent help re: oversupply! Advice & support required!
It is very likely that the reason the block feeding isn't working is be because you are pumping before feeding. That signals your body to make more milk which negates the signals sent by block feeding. The best way to get rid of the OS is to stop pumping completely. You can extend your blocks some too. Nursing in a reclined position can help a lot with the gas and spit up. It can take a lot of tweaking to get the position to work for you so make adjustments as you go.
Green foamy poops alone are not a big deal, the discomfort from gas is the problem. OS babies tend to grow very well because they get so much milk. They can just be fussy from gas. I would give a tummy massage and bicycle legs between every feeding and give a warm bath every evening followed by more bicycling.
Some people are more sensitive to pumping than others, and just a little pumping that early can be disastrous. I am one of those people. That's why it is recommended that you not pump at all the first month or two.
