it doesnt matter that she was on antibiotics and has a cold now. colds are viruses, they dont respond to antibiotics.
i use benadryl for colds too, it really helps the sneezing and watery eyes and runny nose.
i would be cautious about antibiotic use in babies. once you start using antibiotics you build up a reistance to them and then next time they may not work well. besides, i just read a great artcile by the famous dr greene that talks about how many ear infections are virual, and dont even respond to antibiotics and they can be unnecessary.

have you thought about giving her a vitamin c supplement? my son doesnt really get sick much, but if he did, i would probably give him some "emergenc C". i have heard good things about it.
