My son is 16 weeks and has not been nursing well during the day for the past week or so. He shoud be hungry (goes 4 hours between feeds), but pops on and off the breast the whole nursing session (just a few sucks, then pops off and straight back on again). Sometimes he whines and fusses in between. And I don't feel my let down happening like I used to and I don't notice his gulping swallows that used to happen during let down. So my breasts are not emptying fully and I got a plugged duct the other day (which fortunately I was able to resolve). What would be causing this? Is he frustrated at slow let down? slow flow? is it developmental changes? I used a nursing cover today to try and reduce distrations but it didn't seem to help him. Should I pump to empty breasts?
Oh and he does nurse well at the last feed of the day when he is sleepy and I do notice the let down happen then (but he doesn't wake to feed during the night anymore). He is almost 18 pounds and has regular poops and at least 6 wet diapers a day (but not quite as heavy wet as they used to be).
