Mata Sepet Ku

Last weekend Nadhirah woke up with 1 sepet eye. It was not too obvious. At first i thought it may be because of semut. I just sapukan my breast milk to her eyes.

Then next morning, her eye lagi sepet. The bengkak lagi besar. So i decided to take her to the clinic. Doctor checked her eyes and asked a few questions like
- Ada taik mata? No
- Mata dia berair tak? No
- Dia garu-garu mata tak? No

She was perfectly fine. She played as usual and seems couldn't be bothered with her swollen eyes. The doctor didn't find any habuk or anything. So basically, doctor pun tak sure what cause her swollen eye. The doctor gave eye drop to be taken 4 times a day. And Alhamdulillah after 2 drops, her eyes are getting back to normal.
I pun confuse what cause her swollen eye. Any ideas?
