You are right, I am being hard on myself but was seriously panicking...never weighed T but seeing as I couldn't interpret her behavour I needed something to work with! Anyway Yes, was calculating mg-ml just to get an idea of whether she was taking 6ml or 60!
She's been TONS better today and hasn't refused to latch on (tonight she fell asleep on the boob which she has done about 3 times since birth!). I would say shes not much of an eater, I dont even know what her hngry cues are tbh

I used to go by the clock she fed well and put on weight massively, then hit 4mos and started gettign very upset when I tried to latch her on, even went 7hrs in daytime between feeds. Last 2 days she has got better as I said and I have really worked on gettin supply back up (think I may hev OD on water LOL) and my boobs 'feel ' like they are properly producing milk IYKWIM? I have noticed she sometimes falls off right boob and I haev also noticed she doesnt suck hard. NEver sucks for comfort or falls asleepon boob. just trying to outline her behaviour. Yesterday I was feeling a bit panicky as you may have noticed and was spoon feeding water and she seemed to love gulping it down so i tried giving her one of T's sippy cups and she drank a whole cup of water!! I have this inkling in me sayign that my letdown has changed so drastically (used to spurt across boob) that she hasnt leart to suck properly, seriously before she'd sit there lips round boob and it poured into her mouth....not sure that this is making any sense but what I mean is that her behaviour with the cup made me think perhaps it's a slow letdown issue...she cant be bothered to suck when it slows down?
