My little one is 4months and teething to what I do is I put the bobos in the freezer and switch them out all day long the cold helps my little one on top of a cold wash cloth I put that in the freezer and I use a product called Camilla it’s plant base very helpful takes his pain away very fast and top of I use baby oral gel both works wonderful and if he gets to fussy at night because he is in pain I just give him a little bit of Tylenol.
I’d say at this age try to use a teether rather than a medicinal product!
