I think it's the hindmilk that's the thicker fattier stuff isn't it? DD is 7 weeks. She has started to feed on one side of my breast very contentidly for about 10 mins or so then becomes quite frustrated and comes on and off frequently and makes lots of wriggles and grunts and looks frustrated. She's rooting madly and obviously still hungry. If I move her to the other breast she becomes happy and sucks well for maybe another 10 mins or so. Usual feeds take about 20 -30 mins but I now seem to be using both sides in that time. I'm a bit concerned she isn't getting enough fatty milk and can't be bothered with the effort to get it. We've had problems with her losing over 10 % of body weight after birth and although she's now putting on weight, it isn't quite as much as hv would like apparently (was 8lbs 13 at birth and yesterday at nearly 7 weeks was 9lbs 14). ANy idea if this might be as she's just getting the foremilk and if so how to get her to feed longer to get more from one side - she just will not do it!
