Harlie had her 2-month vaccines yesterday. She didn't have a fever, but she hasn't been interested in feeding very much since then, which is very unlike her. She also seems more pale and sleepy today. She was fussy last night but fell right asleep when we put her in her crib. Despite not taking her bottle before bed, she slept 11 hours (she usually sleeps 10). Today, she drank about 2/3's of her morning bottle over an hour and has now been napping a few hours. Not sure if I should wake her up or let her sleep as long as she wants. I'm inclined to let her sleep.
