Spacing out vaccines?

Leah

How do y'all feel about spacing out vaccines? My son is coming up on 4 months where they'll do another round of shots. At 2 months he got them all at once and was SO miserable. He screamed, not cried, but screamed for hours on end and nothing would console him, he was hot and just all around feeling awful. I don't want to put him through that again but i just don't know what else to do. I'm torn. I hate vaccines but I know how necessary they are. What are your guys opinion on it?
