Baby stopped moving

You know how the other day I said Elijah didn't stop moving long enough for a picture? Well tonight he needed a photo op so I guess he took a nap just for that opportunity. Once home from daycare he became really really snuggly and after about 25 minutes he fell sound asleep. We put him in the car seat and still out like a light. We got out at Culver's and he stayed sound asleep. We ordered and got into a booth and laid him down, slept through dinner. Woke up and was happy for about 10 minutes then got super fussy and did the half cry/half whine with the squish nose and scrunched eyes to force out the tears. So a way to the home we went. Continued the crying and whining as he got ready for bed and 20 some minutes after in bed. I think his three gums that he is trying to break through are really bugging him.
