Teething already ? and Molars first ? ooo my

Mia
My LO  I believe is starting to teeth . He will be 5 months next week on the 22nd . Any FTM have this happen? And if you look at the photo I think it's molars that are coming in first. What has anyone given their LO. To help them? Is he too little for baby oragel ? I have the giraffe and some other teething stuff but he doesn't seem to amused . He would play with them for a min and then shove his fists in this mouth . I'm a FTM and I don't know what to give him . Thanks in advance.
