In what way does your breastmilk change from when they are new to when they are older? My dd is almost 11 months and recently she fed from me a good long feed and for the first time since she was tiny she passed out, head back eyes rolling and her mouth open with milk dribbling in a very knocked out/drugged up manner lol!! what the hell is with breastmilk, she doesnt even do that when she has had her favourite meal! she never woke up for about 5 hours! lazy lump, i didnt think breasted milk still held the ko capacity when they are older! lol
