Ds2 had his pre school jabs on Monday. Last night his right arm (where he had tetanus, polio and diphtheria one) came up hot and red. I drew around it and it has spread beyond the line a little today, although it is slightly less red and angry. He is hot and snotty and coughing although happy enough and both ds1 and dh have been unwell for the last couple of days too. I rang the docs this morning and they just said to monitor for 24 hours and that they didn't need to see him urgently.
