Never had this happened before.
So I took out the otoscope to have a look and sure enough she had some bubble like appearance behind the eardrum membrane.
I came to this site and decided to try white vinegar and water 1:1 dilution.
Using the syringe you get with kids panadol, I put a couple of drops in the ear and counted to 5 then drained. Did this to both my ears 1st, an hour or so prior to make sure it didn't hurt... I did find the temperature to be too cold so I used boiled water for the dilution for my daughter's ear... made sure it was lukewarm before using it.
She didn't complain of a sore ear after that. I asked if it felt better and she said yes.
Checked her ear the next day and she had less bubbles. Used the solution again that day and the next day the bubbles were gone. I did it sporadically every couple of days after to be safe.
We bought an otoscope to keep an eye on her ears as she had blockages when she was a toddler.
It does come in handy.
