My pediatrician believes that these things don’t really make a difference and was/is against pouring oils in child’s ear. My son had ear infections but they were mostly because of cold and after I stopped breastfeeding. The temperatures where I live were in negatives so yeah.
Get teething toys, I had a teething sucker/pacifier kind of thing for him, it was his best friend for good 2-3 months till he had his first couple teeth. . I was also suggested to give him a popcicle stick or chicken bone to chew on. It was also helpful. You will have to invest in some teething toys, initially it feels that you are wasting money but it is worth it. Bath books or fabric books that he can look into and chew on.
Lusi I bought all those, he will chew what he SHOULDN’T and never what he SHOULD! what do I do! and his fave are his hands, my hands, the neighbor’s hands, any hands!
Let him chew is hands, dont offer your hand, however, you can massage his gums with your finger. I also tried baby orejel with baby toothbrush, it was very helpful too. Keep offering him the teething toys or things that might feel more natural like a small wooden spoon or a wooden toy or fabric rings. Also, you have to teach him how chew on the toys by putting it in his mouth and allowing him to chew on it while you hold it. Slowly he will learn to hold it and take it to his mouth.
