What to give an 8 month old with a bad cough???

There are two things you can give her, but you should call her doctor to get the proper dosing as it's not on the medicine bottle. Guafenasin is an expectorant, which will help loosen up the gunk and make her cough more productive and worth while. If she has a lot of post nasal drip, she may have an irritated throat which is causing her to cough spontaneously and also keep her from sleeping. Dextro-something or other is the product that is used for this. Be VERY certain you get a doctor's dosing appropriate for her weight (not just age) and get his/her ok because dextro overdose would be an incredibly huge problem. Any medicine, of course would be, but this in particular. These products are in Robotussin DM I believe and other various Tylenol cold type products. I wouldn't get anything that had any other products in them that are not necessary, mostly because some are inappropriate for young children - ie diphenhydramine (benadryl) and psuedaphedrine (sudafed) and other products that are similar - very unsafe. I've used the guafenasin and dextro....with my son for this type of situation, getting an updated dosing every few pounds he gains. Most doctors are fine with you giving this to them, but get the dosage from them.
