My one year old son just got his 12 months well baby shots, and that night started gagging and puking on everything he ate. He s normally a really good eater, but since his shots. has not been able to keep anything down! I ve tried simple things like a tiny piece of cracker, and still puked. I don t know what to do. He s drinking fine and keeping milk and juice down, but nothing else! My poor baby hasn t eaten in almost 3 days. Please help!!!
