DD1 is 2.10. She had pneumonia about 6 weeks ago. Nursery phones not long before she was due to be picked up to say she had a rash and a temp of 38 and asked if they could give Calpol, DH said yes. When I collected her up she was very upset and the rash was still there. She perked up a bit when she came home and the rash has gone but we took her temperature again before bed (about 2 hours after the dose of Calpol) and it was 39. She's asked to go to bed (something she never does) so we've put her to bed as normal but will continue to check her temperature.
Should we be concerned that her temperature is rising even with the Calpol?
