My 19 week old son has been eating every two hours, for about 20+ minutes since he was born. When I'm at work, I pump and he eats 3.5 oz every 2 hours- then seems to power nurse on my days off. The past two days, instead of power nurse, he would nurse for MAYBE 10 minutes. After that he either pulls off/falls asleep/ or starts to play [ pulls off- looks at what's going on-latches back on for 2 seconds just to decide he doesn't want it-etc ]. BUT afterwards- I don't feel full anymore so it's not like he didn't "eat it all" per say. Then today, instead of every 2 hours- he would go maybe 2.5 then slightly fuss [ which, I'd immediately offer since I didn't want to mess up his schedule ] but normally he makes it KNOWN when he's hungry. At first, I thought maybe he's just eating quicker because I heard they do eventually not take as long nursing but when I went to pump tonight [ I always pump at night because this is when I usually get home from work and he's always asleep- so even on days I don't work- I pump at this time] I got MAYBE 3 oz out of BOTH SIDES [ normally I get at least 3 each side ]. What's going on here? I'm going to have to pump more tonight/tomorrow morning before work because now I don't have enough but...maybe he won't need as much? UGH! Is this messing up my milk? How could he need less all of a sudden? When he does pull off- he's completely content. I also want to add- he is exclusively BF- no solids/water/etc. PLEASE ease my mind!
