Hi there,
Ear pain is one of the worst pains, as there is not much bar analgesia that you can do with it. i am so sorry for your LO having to go through this twice in about one week. Is he on antibiotics for the infection?
Best I can suggest is that you give him regular pain killers. I know it isn't always something as a parent you like to do, but if that is going to help him, so be it.
Regarding the feed. I think sometimes it isn't the nutrition as much that helps him settle, it is the mechanism of swallowing that probably helps relieve the pain in the ear. Think about how if you fly in an aeroplane and your ears pop due to the change in altitude and the increase in the pressure in you ears. darn painful But what do you do to relieve it? Yawn, suck a sweet or drink water. The movement helps the eustachian to open up and equalise the pressure. Probably what helps your LO too.
If you don't want to feed, absolutely fine. But if you could perhaps do something to help emulate the movement or swallowing, that alone might help. But I am sure there are more experienced mommies who will be able to give sensible advice.
Good luck!!!
