My ds 14 weeks has started behaving very strangely when feeding over the last 24 hours. On one particular boob he continually pulls off during feeding. He doesn't cry, just looks about, talks etc. for about 30 secs then immediately wants to go back on he does this whether this boob is offered first or second in a feed and generally feeds normally on the other side. He has once done the same thing on the other side too. Not sure what's going on. He doesn't seem at all distressed so don't think the position is uncomfortable for him. Any ideas anyone?
