My baby boy is 15 weeks old and at his last doctor's visit (about a month ago) weighed 11.4 pounds and was about 24 inches long.
He breastfeeds exclusively while I am home with him and feeds about 6 times in a 24 hour period. He has at least one dirty/poop diaper a day and at least 5 wet ones. Because of low pumping output I have had to supplement formula into my pumped breastmilk (with the return to work and him in day care).
With a bottle he drinks about 5 oz every three hours (that is 4 oz of breastmilk and 1 oz of formula). I never wanted to give him formula but I'm just not pumping enough (using a Medela swing and a manual; I actually have had better luck with the manual. Also used an Ameda Purely Yours and it didn't work any better).
I pump at work every 2-3 hours but can only get about 2 oz per session (and that's with both breasts pumped). Obviously, I'm not pumping enough on one day to be able to provide him with enough milk for the next day. I have tried watching videos of him, listening to relaxing music, applying warm compresses, drinking Yogi's Nursing Support Tea, etc.) but nothing helps. I know I have the milk in there (I can feel my breasts preparing for feeding even when I'm not with him; a tingling sensation and my bra pad is usually soaked with leaked milk) but when I pump nothing comes out.
I wanted to breastfeed until at least 6 months but now I don't know if I'll make it to 16 weeks. It is depressing.
Additionally, my little son is now in the habit of playing with my nipple at feedings. He will place it in his mouth, suck quickly, and then move his head. He'll do this repeatedly until, frustrated, I put him on the other breast. But I'm concerned he's not draining it completely (I can still manually express milk from that breast) and so because he's not draining it, it won't continue to produce.
I can't remember the last time I was engorged. Or even felt full. And he sleeps a good six hours during the first part of his night. Used to be that I would become engorged after three hours.
