Megan sick?

Megan has had projectile vomit/spit up in our house two times. I didn't think much of it because I expected it every once in a while. When we were in Toledo for the naming, she did it 4 times at my sister's house. I called the doctor and they said to feed her fewer ounces more frequently. So she went back to day care on Wed and everything was fine. On Thursday she did it again right before I picked her up. Well, when she did it again on Friday day care asked me to take her to the doctor. I called the doctor's office and they said to just come right in. The doctor looked at her for a few minutes and decided that he wanted her to have an ultrasound to see if she has an obstruction. He thought it was unlikely, but could be serious and require surgery. I was pretty sure he was overreacting, but off we went to the other clinic for the ultrasound. Sure enough, the tech saw that everything was fine. They again repeated, few ounces and more frequent feedings. They also said to hold her upright for 30-45 minutes after eating. The weekend was great but we exclusively bottle fed. Monday morning I decided to nurse again. I weighed her before and after and she had eaten 6 ounces. That was after I limited her time! Well, she spit up a little bit but nothing projectile. She then had no problems at day care today. Hopefully this is the end of the projections!
