If I were a betting girl I would bet on the penicillian. It is a real problem child when it comes to allergic reactions. Glad you and she are ok. Not surprising that she is so lethargic really given the phenergan. Hope you are all ok now. Take it easy won't you. It can be so exhausting taking care of a sick baby. You need to mother yourself a bit too. You all gonna be ok.
