Allie's not feeling good

I took Allie to the Dr today. She's been throwing up for the past 2 days. She weighed 16.05lbs. so she's gained 1 lb since July 9th. He just said its a stomach thing, and that there is nothing for him to give her. He told me to go and buy some Pedialyte and give that to her. I got the Cherry flavor and she loved it :) Now, she's sleeping in my bed.
