How Do I Stockpile and Budget Diapers for a Deployment?
4 min read
To get diapers right through a deployment, buy ahead by size, budget about $70 to $100 a month per baby, and stock a range of sizes so you are not guessing when your baby grows mid-deployment.
How many diapers will I go through?
Plan on a lot. A baby uses 8 to 12 diapers a day as a newborn, settling toward 8 as they grow, which is roughly 240 to 360 a month and about 2,500 to 3,000 in the first year (National Diaper Bank Network, 2025). Map that against your deployment length. A six-month stretch for an infant runs on the order of 1,500 diapers. Build the plan around the real count, not a guess.
What will it cost, and how do I budget on one income?
Budget about $70 to $100 a month per baby for disposables, roughly $840 a year (National Diaper Bank Network, 2025). Prices have climbed. A package that ran about $16 in 2019 was closer to $22 by 2024. On a single income during a deployment, treat diapers as a fixed monthly line, the same as rent or the car payment. Buying a few months ahead when cash flow allows locks today's price against the next increase.
Should I buy the whole deployment up front?
No. Buy ahead, but not all at once, and not all in one size. Babies grow through sizes on their own schedule, and a stockpile in the wrong size is money sitting in a closet. Buy a few weeks past your baby's current size and keep your receipts. See how to stock up without wasting money on the wrong size.
How do I size up so I am not guessing at month four?
Size runs on weight, not age. See what size diaper your child wears. Keep the next size up on hand before you think you need it, because a diaper that is suddenly too small means leaks and midnight changes with no backup. When in doubt, size up. A slightly loose diaper leaks less than a tight one and buys you room to grow.
Where should I buy to stretch the budget?
On base, the commissary sells diapers at cost plus a 5% surcharge, usually well below civilian retail, and the exchange is tax-free. See is it cheaper to buy diapers on base. Warehouse clubs and store brands lower the per-diaper cost too. Compare cost per diaper, not the box price.
What is my backup if I run short?
Have a fallback before you need one. Your branch relief society, base pantries, and local diaper banks can bridge a gap, and a pay hiccup or a shutdown does not have to leave you short.
