Dd and ds were ill for most of Nov with a vomitting bug. In both cases it lasted a week, went away for 4-5 days then came back again. Dd has been at school for over a week so we thought we were all clear. This morning she was sick again. Later she said she was cold and her fingernails and lips were blue.
Help! Should it be going on this long? I am at my wits end.
