30C is about 86F. It's really a very high temperature. Re "先给孩子热出痱子,再搽药,受两茬罪么?" You really don't think there is any side effects for that? It really depends on your priority - do older people come first, or do young kids come first? By the way, is your kid an infant? If so, high temperature would greatly increase the chances of SIDS.
