The hospital will have asked a lot of questions about walking, bathroom trips, and stairs. Fewer people ask about the tray. That is where eating and drinking often slip first, and it slips quietly, because nobody is sitting with your parent when the plate comes back half full.

Local option: New Plan Care gives families in the St. Louis area in-home help so a parent can stay home: companionship, help with bathing and dressing, meals, and overnight care. Call (314) 405-0887.

Before the car leaves, ask about food and fluids

Read the discharge packet for any written diet or fluid instructions. If it says nothing, ask the nurse or discharge planner directly: what should eating and drinking look like at home, and what should we report? Hospital discharge planning rules expect the team to address what the patient needs once they leave, so this is a fair question (Medicare's discharge planning conditions, 42 CFR 482.43, readable on eCFR). Get the name of the office or line that answers these questions and write it on the same sheet as the medicine list. Ask who calls the doctor if intake looks wrong, and whether that is you or the office.

Make the tray test for three days

You do not need a chart. You need a sheet on the refrigerator with three columns: meal, roughly what was eaten, and what was drunk. Fill it in for the first three days home. Note who made or set out the food. A glass of water poured and left full tells you as much as a plate sent back untouched.

Look for patterns, not one bad meal. Watch for food that goes into the refrigerator and comes back out unchanged, snacks that never get opened, a cup still full at bedtime, and a parent who says they ate when the containers say otherwise. Also watch for meals skipped because standing at the stove is hard, or because the food sits where your parent cannot easily reach it. Those are setup problems, and setup can be fixed.

Give the job to one person

Pick who checks the sheet each day. It can be you, a sibling, a neighbor, or a paid helper. A non-medical helper can shop, put prepared food where your parent can reach it, and keep the sheet up to date, which are ordinary household errands. What the helper should not be asked to do is decide how much your parent should eat or drink, or judge whether a change is serious. Those judgments belong to the family, the doctor's office named on the paperwork, and the pharmacist if a medicine is part of the picture.

Make eating easy before you make it a conversation

If your parent is turning food down, lower the effort first. Put water and easy foods at the front of the refrigerator, open the containers, and keep a cup where your parent usually sits. Ask what they would actually eat, not what they should. A short conversation works better than a lecture, and a plate that is already in reach works better than either. The National Institute on Aging publishes plain guidance on eating and nutrition for older adults, and MedlinePlus has pages on nutrition for seniors. Read them for the general picture, not as a decision about your parent.

Know when the sheet becomes a phone call

Call the number on the discharge paperwork when the pattern holds for more than a day or two, when your parent is eating well below what the instructions described, or when drinking drops off and stays off. Do not wait for the next appointment to say so. If your parent cannot keep anything down, becomes confused, or seems suddenly unlike themselves, follow the emergency instructions on the paperwork and call 911. Keep the doctor's office number, the hospital's discharge line, and the pharmacy number in the same place as the sheet.

Where to look next

If the sheet is hard to keep up with, or meals are the piece nobody owns, compare options on Local Help After a Discharge. Check the rules behind this guide on Sources.
