i hope barb or MR pop in, but i think how much water you drink doesn't hugely affect supply...i remember something about the comparison to women in 3rd world countries who get very little to eat or drink & they successfully BF for long periods of time??

it may just be that shae is feeding some of the time for comfort or for a growth spurt etc. my DS has gone back to feeding every 2 hours (and sometimes every hour) overnight for the last 2 months.l in his case i'm sure it's not supply - for him it's comfort & help to get back to sleep when he comes out of a sleep cycle - not sure if these things apply at 3 months? i have founds times where he seems insatiable & i'm pretty sure heaven had a thread recently where he DD was feeding constantly during the day for a while & she's older again!
