So it's red and hard here, where she got her shots. Should I be worried?

Get a warm wet rag and apply it. Did she get shots at 1 month?? Does she have a fever? Is she fussy??

She got her two months shots

@rmreed, she is fussy but no fever

Massage it lightly warm compress should go away in a day or two

Nope perfectly normal it's just the vaccine doing its job, just give her some Tylenol to help with her "pain"
