Dc2 has developed a coldsore today (but dc1 never had one, so I'm new to it). I know coldsores are dangerous in babies, but I don't know at what stage/how old it isn't a big deal anymore. Dc2 has had all jabs due so far.
Have phoned hv for advice earlier but no reply, so message left. It's now after five, so won't hear from her today. Do I need to do anything more now?
