Sorry, jumping on a little late, but wanted to ask a question...does your LO have their two year molars yet? DS had something like this for about a month over the summertime (so around 22 m/o, I know...a lot younger) and sounds a little similar but wanted to make sure that it wasn't being overlooked!!
(Don't know if the other girls know you a bit better and therefore know if your LO's teeth are all finished
)
