My Emma's sick. I think she has a nasty cold. I gave her dimetapp (Pediatritian recommend) last night and she coughed so hard she threw up everywhere!! She has no fever but woke up just about every hour during the night. Do you mommys think I should make her a doctors appointment or hold off for a while?
