Well I rang the clinic today and luckily the baby was in a different ward, pheww.... still doesn't mean it won't get it, but it is less likely. Thing is the lady said if the baby was in the playroom with us at the same time it is still possible, but I don't think I was ever in the playroom with anyone else except our ward except once that I remember so hopefully that was not the baby. Crossing my fingers that he does not get it, but looks promising at this stage.
