GEorgie is 8 weeks and had her first immunisation yesterday and the rotavirus serum. She has just done a massive projectile vomit following her last feed. Should I be worried, should I take her to a doctor? She has been fine, she has just gone to sleep but she is due for a sleep and she just had a bath so sleep makes sense but she probably went to sleep easier than she normally would. I've been trying to ring the helpline but it is engaged.
