My LO is almost 15 weeks and exclusively bf...the past 3 nights he has been screaming, pulling off the breast and waking up every hour screaming at the top of his lungs...last night I was at my wits end...he wanted to nurse but was frustrated that the milk was not coming fast enough. I want him to suck to up my supply but he refuses....finally I gave him 2oz of organic formula and 1 oz of breast milk mixed...it was all i could get from my pump after 20 minutes...he sucked it down in record time and slept for 6 hours straight...the first time he has done that in the past week. I cannot get my milk supply up for him. If it does not come quickly like in the day time, then he refuses to nurse...I have no idea what to do...I feel like a failure for giving the formula...I have been crying because all I want to do is bf my son...how do I get him to continue to nurse? I have tried it all...the teas, tinctures, fenugreek, reglan...I am doing all I can and still no change...my ideal situation would be to nurse him until he is 2...how can I if I can't even make him happy when he is under 4 months?
