I’m not one to complain I love my son so much. He got his 6 months shots on 3/19/18

And of course with that came fevers. Maybe that’s why he has become more fussy and clingy. He doesn’t want to play much like he used to on his own when I would quickly do some stuff and then we would play and hang out together. I’ve been trying to teach him independent play. He has been a very chill baby and always didn’t mind playing independently too. But now he won’t even let me leave the room. Right now I’m in his play pen and he’s playing some but he’s crying. I’m not sure what to do. I fed him changed him checked his temperature. All is fine.
