My son just had his 2 month shots. Can they make him more sleepy?

Thank you @bodaciousb6

just let him sleep. he'll wake when he's hungry @heavenwings

So would you let him sleep or offer him food? He ate last at 8pm and I just gave him his medicine I mix with 15mls of milk which he took like a champ. He is now falling back to sleep.. @bodaciousb6

@heavenwings, yes
