My 1yo over the past 3 days has been throwing up in the night (1st day 4 times and last 2 nights once). In the day he is very happy etc and until he throws up is sleeping well (throws up around midnight for the first time and asleep since at least 8pm) and then he's happy again and goes back to sleep. Calling gp today but I was wondering if anyone has experienced this... is it reflux? How did you sort it?
