Hello T.,
I just want you to know that my little girl, my first, had this problem as well,she threw up everytime I fed her, and then I learned that I was over breastfeeding her, or her stomach was abnormally small, so after I had nursed her on both sides, and after she threw it all up, then I would feed her what was left from the both and she would hold it down. I knew I was overfeeding her because when I started pumping I was producing 4-8 oz of milk on both sides, and everyone knows that a newborn doesn't need that much milk! Nobody knew why she spit up all the time, I had to figure it out after baby number three, but she did get bigger and was able to hold more down. Once she got to one and a half ( when I decided to move her to a toddler bed, I did the same thing you did with your first four, I let her cry it out at night, and yes, she did throw up every night for maybe four nights, BUT, she did get used to what I was doing, and she just started going to her bed and falling aslepe on her own. when she threw up, I would go in there and say nothing but,'it is bedtime Loralai', and then clean up the mess, and close the door and walk out. (So you know though I only nursed for 11 months, and had her crying herself to sleep earlier to sleep through the night at a much younger age, maybe 3-5 months) It was hard as ever, but she did learn fast, and believe it or not they don't like getting sick any more than you do, so they learn to control it, at least that is what Loralai did. If Loralai gets really upset, she does occasionally get sick, from now that she is 6 it happens very rarely. I just knew that I had to get her to learn to sooth herself because I ran a daycare and needed sleep very much, like you. It does get better within two weeks though, at the worst. If you have any questions for me just write me and let me know and I'd be happy to answer them, good luck, L.
