Hi DD is 8m and bf has been going really well up to now. Started solids at 6m, but she's not really that keen so still mostly just playing with food (although some does come out the other end! 
Last 4-5 days I've been having a lot of trouble with my supply and also my milk let down. It's just suddenly gone!
I know I'm not letting down milk because
- I almost always feel the first let down
- DDs sucking pattern is just sucking, very little swallowing, I know the change when the milk starts flowing
- DD gets grumpy as there's no milk!
Mornings are not as bad, usually starts flowing after 2-3 mins, afternoons take longer but evening feeds have been a total disaster, no milk and very grumpy baby after 15-20 mins sucking (and also sore nipples 
).
I have tried relaxing, thinking of waterfalls, imagining the milk flowing through my breasts... I generally feed in the same chair (DD is too nosy to feed different places anymore), it feels like it's almost there but just not quite!
Supply also seems to have taken a nosedive, boobs suddenly very soft and wrinkly, not filling up much and DD seems 'finished' very quickly and demanding the other side, and then the first again.
DD's weight gain has also stalled the past month or so.
Any ideas??? TIA
