More fussy?

Petranella

My 5 week old has been more fussy since yesterday. He woke up in the night for feedings and went back to sleep without a problem. But this morning he is starting to be more fussy like yesterday. I even took him on a car ride and he still was fussy. He normally loves car rides and falls asleep.

I checked his temperature too and it was 98.1 so I’m not sure why he’s acting like this?
