Hi, SPK07- another caregiver chiming in- if the thick mucous continues for a week, ask for a portable suction maching prescription- it will help alot to clear his mouth of mucous.Since he has many more rad. tx's to go, this is all likely to get worse for awhile- hard for youall to hear- but most folks here have gotten through it. You need to be prepared to what "might happen" so you are not caught by surprise. Don't know which one of you is the more vocal, but someone needs to be on top of symptoms as they occur and tell the Docs or nurses when help is needed- especially before a weekend. That can save alot of grief. I would suggest you get some unflavored Pedialyte in the pantry [in the kids section of gro stores], some Welches grape juice, Gatoraid,and start seriously tracking the amount of liquids [in ounces] he is consuming daily. Always count the water you flush the peg with after feedings or pain meds, and have him use liquids between peg nutrition feedings.Do you have a goal set each day for intake? The next 4 weeks are doable, but will be much easier if you are doing a good chart and he is understanding about why it is all so important to his getting well. It really is a "team effort"! Good luck, Amy in the Ozarks
