any tips for teething?

Kayley • 24 years old, I have a little boy who’s 4 and I’m TTC my second baby!! 👶🏻
My son has been teething since 3 months old, but it has recently got worse at 4.5 months old. I use teething gel, teething powder, Amber bead anklet and have a teething ring (he can't hold it properly yet so I have to put in his mouth), is there anything else you can think of that helps teething?
