Help! I'm running out of clean clothes!

I always say, "Ainsley is completely opposite of her brother." well, I think I am wrong. She,like Colton, seems to have reflux. We went yesterday for her 6 week appt. and dr. T put her on Zantac for babies and told me to thicken her feeds so we have been doing that for about a day and I just got projectile vomited on but this time instead of plain formula, I got hit with chunks thanks to the added rice starch in her formula! Yeah! I'm hoping it takes a couple of days for the meds to kick in. In other news, she got three shots yesterday and weighed in at 11 pounds 4 oz. (90%) was 75% in height and 50% in head circumference.
