Что случилось с детьми? У обоих высокая температура, но других симптомов нет. Беспокоюсь!

My youngest 2 woke up totally happy and healthy this morning, by noon the older of the 2 wasn't looking too hot and then by bedtime they both have high fevers but no other symptoms but its making Lydia inconsolable 🥺 i gave her tylenol but until it kicks in my heart is breaking for the little lady 😭
