Hello. My son is 3 years old. He had a fever and was feeling unwell a few days ago. He has since been better. This evening, he seemed fine (he went to daycare today). All of a sudden, he started saying that he wasn t feeling well. I took him to bed and he became very pale and lethargic. No fever, slightly heavier respiration. He is asleep now and I am very concerned. Should I take him to the emergency room or monitor him and wait until the morning? Thank you.
