I have used the service a number of times, mainly for my son. They are invaluable out of hours when you are worried about your child and feel a drs call is an ove reaction.
I will however mention.the time that i rang them when my son was four weeks old and projectile vomiting. I got basically dismissed as a neurotic first time mum. Being persistent i took him to my gp the next day, when he was admitted to hospital and,placed on a,drip. He had an operation the day after and was fine.
Since then i take their advice with a pinch of salt . But they are great to be able to blame on the very few ocassions i have used the out of hours service.
