Hi
My 11wo DD has started sleeping for longer periods at night. She goes down at approx 10pm and wakes between 4am and 6am for a feed, and then goes back to sleep until 9am ish.
The first few mornings she did this my boobs leaked a lot and were HUGE and painful in the morning. Recently though they are not as full in the morning and I have noticed that I have less milk in the evenings so she is a bit more fussy in the evenings than before. But then again, she must have a fairly full belly at bedtime to be able to sleep for so long 
I have always had a great supply up to now, a little too much if anything, I was constantly leaking! So is this my body just adjusting to her needs, or should I be trying to up my supply? I am just worried that if she has a growth spurt I will have nothing to give her
Thanks
