How many diapers do you need for twins?

One of the big expenses with raising twins is diapers. From the day they are born until they master potty training and keeping their pants dry overnight, you’ll need to buy diapers.

Twin Diaper Usage

Newborns average about 10 diapers a day per baby. So your newborn twins will need about 10 diapers X 30 days X 2 babies = at least 600 diapers for the first month.

After about a month diaper consumption goes down to about 8 diapers per day. You’ll need 8 diapers X 30 days X 2 babies = at least 480 diapers per month for a few more months.

After three to six months, your babies should fall into a regular pattern with more predictable diaper usage. The blow outs and leaks of the newborn days are gone and you’ll see a pattern emerging. From 3 months to 1 year you should wean down to about 4-6 diapers per day per child.

So based on averages (your twins’ usage will vary) you are looking at using about 2,000 diapers by the time your twins turn 6 months.

After the year mark, diaper use is usually down to about 4 a day: one change when they wake up, one before naps, one before bed, and one for the random poop that happens every day at unpredictable times. So your toddler twins will need 4 diapers X 30 days X 2 toddlers = 240 diapers per month.

This means your twins could use close to 3,000 diapers in the year between ages one and two. (Makes you want to potty train early, doesn’t it?)

Diaper Transition

Once your twins potty train, you’ll be free from the traditional diapers. However, in some cases, you might need Pull-ups for nap times and overnight sleeping until they master the overnight dryness too.

Unfortunately, Pull-ups (and especially the overnight extra absorbent kind) tend to be more expensive than regular diapers. Fortunately, the volume of diapers during this transition period is cut in half.

Diaper Budget

You may want to establish a generous diaper budget for yourself as you stock up on diapers during pregnancy and maintain regular diaper use through the first two years or so.

What should you do with that money after you don’t need diapers?

You’ll see food consumption rise as your twins get older. That increased expense will likely offset any savings you see in no longer buying diapers.

Alternatively, you could start saving the money you did spend on diapers in your twin’s college savings funds. That way when it is time for college, you can remind them that they don’t have enough money because they refused to potty train until they were four.

Your twins won’t be in diapers forever! I talk more about potty training them in Chapter 12 of my book, the Dad’s Guide to Raising Twins: How to Thrive as a Father of Twins.

  1. Tom says

    And that, my fellow father of twins, is one of the many reasons why at about 10 months, we switched to cloth.

  2. says

    @Tom – cloth diapers are definitely one option. Did you use a cleaning service or take care of everything yourself?

  3. Ben says

    Wow, the numbers really put things in perspective! We have a couple of hundred to start with (always a good idea to have baby shower guests bring some), but looks like we’ll go through them rather quickly once our twins are here!

  4. Tom says

    I have to recommend cloth diapers. Spend a few hundred bucks up front, and have diapers for as long as your kids are in the. We even passed down from our twins to our next one, saving more money. Let’s not forget the environmental impact of disposables vs cloth too.

      @Tom – thanks for mentioning this again. You make good points about re-usability and environmental impact. How many cloth diapers do you have in your rotation? How often did you have to wash them?

  5. Seth says

    I’m an expecting dad of twin boys. I see that these comments are pretty old, so you’re all well in advance; are there any tips, ideas, or suggestions that you might care to pass along? My wife is just about 7 months pregnant, I’m so excited but am starting to worry about expenses. Please share anything that helps!

    I am expecting twins in Feb. I like to consider myself a “preparer aheader” but when it comes to stocking up on the various sizes of diapers (or registering for them) I am stumped on how many to get in what sizes. Any helpful hints? Thanks!
