My DD (5) often vomits with anxiety, today was her cousins birthday party, she’d never been to a big party before and gets very nervous around other children. She went to football club this morning, gagged when we got out and brought up a little bit of liquid, then when we got home she vomited loads and brought up lots of orange juice she’d drank at football club. She hadn’t eaten that morning but she rarely has breakfast. She said she didn't feel poorly she was just nervous about the party, DH insisted it was anxiety and said we should go, as did all my family. She's eaten fine since, loved the party, yet I'm still on edge now at 6pm. Do you think if it was a tummy bug she would have been sick again?
