I was wondering about supply issues, same thing happened to me with DS (and DD for that matter). I can't remember the name of the LC that came out to me (we're in the same local area, so you may score the same one perhaps?) she recommended the forumla top ups, and keeping a diary of feed times and how much breast milk he took (EBM or b/f) and the duration, and I had to start offering and recording each formula top up too. I may have offered 100mL but if only half that was taken that would be recorded and the rest discarded, until the 100mL gets close to always being finished, then i upped the top ups as DS grew. Through expressing I saw my supply dwindle quite quickly to nothing, so I gave up *red face*.

And yeah, it did make me feel bad (as I'd tried those lactation cookies *yummy*, and maxalon, and one other prescription too), but for me it was about what was in the best interests for a healthy baby.

Good luck hun!
