Feverish!

Received a call from hubby that MIL had told him Sherry is a little feverish. Her temperature was 38.3 degrees. She was wondering if I’m going back with him, if yes, will have to try to be early. But I’m not, cos I’ve arranged to meet Kat at the same time at our usual place.
When I’m home, quickly take her temperature, 1 ear is 37.9 degrees and the other is 38.1 degrees. We concluded that she could be just having a slight fever. I took out the fever medication from the fridge and noticed that the medication were dated in May n June. I was afraid that it may have expired, so called the clinic to clarify with the nurse. But the nurse was also not very sure about this. The doctor had told MIL that it can last for 6 months if, it is unopened and is in the fridge, but the nurse kept saying, three months. So which are correct lei, can anyone tell me?
But anyway, we had decided not to give her any medication since it’s a slight fever. If the temperature had gone too high up in the night, then we’ll give her 1 dosage of the medication.
She still can play as usual and still walk around the house as usual. She has the slightest sign of being sick. Hmm… so I’m still wondering what causes the fever. It was round 9pm plus that she decided to sleep. So brought her to wash up, brush her teeth, and changed into her pajamas. She had surprised me by finishing all her milk which I thought otherwise.
Tonight will be a sleepless night for mummy, who will have to keep waking up to see my little girl… Tired lei… hai.. Hope she’ll be fine tomorrow…
