My son is teething really badly. Teething toys aren't really helping. Are there any teething gels or powder that you would recommend?

Never heard of any teething powder. There is teething gel, Dentinox. I won’t recommend that though.. Have you tried this kind of teething feeder? My girl loves it. We always put frozen/cold fruits inside. It’s cold and sweet, so they will usually accept it unlike regular teething toys. Sometimes we freeze my bm and put it inside for her to suck on it also. Can be used even when they are older, not just when teething. Sometimes sick, no appetite. Then we freeze yogurt and put it inside the feeder for her. https://welovesupermom.com/products/30305-sassy-teething-feeder-2-pack-teething-feeder-replacement-bags
