DS had his Hep B booster yesterday afternoon. He seemed fine all evening (a little tired) since bed (9pm) he's only woken up twice (2am & 5:30am) which is odd b/c he's usually up at 12am, 3am, and 6am. He's only eaten 4oz since last night.
He's breathing fine, but just seems exhausted and not interested in eating. Did anyone else have a similar reaction?
