Hi, Miriam, now that youall have started the journey, here are a few more hints. Get a couple of bottles of unflavored Pedialyte [baby section in gro store] to keep on the pantry shelf. Anytime your Dad gets a little low on the amount of hydration he gets each day, put that down his peg. [someone will need to start charting all the ounces of peg food and all liquids he gets daily. And the water used to flush his peg tube or flush pain meds counts as hydration too]The Radiation Doc or his nutritionist should have given you a goal for him to meet daily in both areas. We also kept Welches grape juice, apple juice, etc. handy for liquids. Some things may burn his stomach so you may have to start experimenting. Let us know where we can help you with more ideas.
