Girls, can you please tell me how to get better faster? My daughter and I started getting sick today, and tomorrow we have a big party at a restaurant ??? We're at 37.8 degrees now, not fevering, drinking warm water and breastfeed her, she goes without diapers, capricious, wants to be on my arms all the time, do you think we will recover until Saturday?
