firstly you are doing an awesome job, i have been through the NICU journey, it aint easy
my son was a 30wkr and has just turned 1 and is still breastfed but i, like you suffered supply issues, i started using motillium when L was about 4w as i too was getting lots the first few weeks then no matter how much i pumped i was getting less and less. (im unsure if you can take it with other meds tho check with your GP?)
the lactation cookies are good (eating the dough raw actually works better then cooked cookies, depends if you can stomach it)
have you tried taking blessed thistle and fenugreek capsules from the health food store? 3x fenugreek 3x a day and 3x BT 3x a day? it will make you smell like maple syrup lol
wishing you all the best for you and your LO's journey.
i know how hard it is being apart from your baby, its like a piece of your heart is missing
i hope its all smooth sailing for you, we have a few scary things (little bumps in the road) but L is now doing well, hes a little behind, even for his corrected age, but hes an absolute joy and his sisters adore him
