Ds (16 weeks tomorrow) has always fed every 1.5-2hrs during the night and used to be just as frequent during the day. He was starting to settle with less night feeding, then had his jabs in week 14. Now he seems to have reverted to 2-hrly feeds during the night, but it's days I can't figure out.
He latches on eagerly enough, sucks for about 30secs-1min, then twists himself off and starts complaining bitterly. (Shouting, grizzling, or if it's late in the day, crying.) Yesterday I didn't force the issue and he only fed at 8:30am, 2:30pm and 9pm.
Lots of times during the day he seems hungry to me, like right now he is chewing his arm and complaining loudly, but if I pick him up he'll do the same thing.
Hang on I'm just going to try, he hasn't fed since 4am so he might go for it now...
