I hope this helps. Also ask your pediatrician if your baby can have some Tylenol and IBU. Tylenol for the discomfort and slight temperature and IBU for inflammation.
Are you sure it’s not reflux / silent reflux? That can cause the excess saliva and the cat napping
@Shannon thanks for this, will have a look and ask.
I bought my daughter this. https://mossandfawn.com/ She’s not teething yet but what I read on their product is great. Not only can it be a teeth ring. It can also help with some motor skills. It is also used for introducing food safely. I bought the ring and the ice tray. The ring comes with a couple of sizes. Like the nipples for bottles. I cannot wait for her to try it!
