4 month shots

Paige
How did everyone's babies handle the 4 month shots?? We are on day three and my son is still not acting himself.  His eyes are droopy and he's been sleeping so much more.  When he is awake he just complains the whole entire time until he falls back asleep.  He handled the 2 month shots really well - no reaction at all.  Wondering if anyone is experiencing the same!
