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?)
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.
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.
