Crabby pants 😒

I swear the last week Jaxson has been SUCH a crab! My daycare lady even mentioned something because she thought he might be sick because he's been soo fussy, throwing tantrums, crying, whining. It's like every waking minute he's either crying, screaming or whining. He's not going through a leap right now either. His sleeping is fine, he's still sleeping 12 hours a night. The other night he got home from daycare and just screamed literally until he went to bed. I tried tylenol, we fed him dinner and he kept throwing it and screaming. He's a monster! I'm wondering if he's teething really bad right now but I don't see any other teeth coming in.
