Are you trying to build the diaper stock pile in your home? Read below for what works for us and our family of three kids!
We currently have two out of three kids in diapers. To say that we stock up on diapers out of necessity is an understatement. Thankfully, I’ve definitely been around the diaper block a few times to know how much I need to stock up on in each size.
All three of my boys were born around the same weight (~8 lbs.), so that helped immensely with knowing how many diapers I need in each size. While each of them are growing at different paces and have different body types, during the first year they’ve been pretty similar in the different diaper sizes.
Full disclosure, this is just a guideline of a diaper stock pile that worked for our kids in the first year. Obviously, each baby is different, but you can use my tips and info to have a rough estimate of how many diapers you will need in the baby’s first year of life.







With three kids, I’ve been around the diaper block a few times now. We’ve tried all different brands and haven’t had any major issues with any of them. But, our go to brand has always been Pampers. No endorsement here, it’s the brand that they gave us at the hospital and most of my baby shower gifts were also the same brand. The different Pampers diapers have worked for our three boys at different stages in the first year and into toddlerhood.
All of my babes have super sensitive skin and we’ve never had issues of irritation. The fit of the diapers is perfect for each of their bodies too, C runs around all day long and is comfortable and dry with the diapers that are leak protected for up to 12 hours. Baby B is just starting to squirm and wiggle on his tummy and rolling over all day long too. They move so well with him while still providing coverage and comfort.
I try to buy them in bulk whenever possible at our local Costco or BJ’s Wholesale.
Here’s the Diaper Stock Pile – The Ultimate Guide for Baby’s First Year that we use in our household:
- SIZE NEWBORN: UP TO 10 LBS. (4.5 KGS.), Good during MONTH 1, 1 LARGE BOX (~150 DIAPERS) We actually didn’t have to buy any newborn size diapers ourselves. Between what we brought home from the hospital and small packs that were gifted to us by friends and family. The first month was easy breezy in the stock pile department.
- SIZE 1: 8-14 LBS. (4-6 KGS.) Good during MONTHS 2 & 3, 3 LARGE BOXES (~650 DIAPERS) All of our boys were in size 1s for about a month and half or so. They were all around 8 lbs at birth and back to birth weight and then some in month 1. By month 2, all three were around 12/13 lbs and solidly in size 1 diapers.
- SIZE 2: 12-18 LBS. (5-8 KGS.), Good during MONTHS 3 & 4, 3 LARGE BOXES (~600 DIAPERS) This is the size that all three boys wore for the shortest amount of time. I’m not sure if it was their size or the fit, but we didn’t use size 2s for more than 1 or 1.5 months.
- SIZE 3: 16-28 LBS. (7-12 KGS.), Good during MONTHS 5-11, 6 LARGE BOXES (~1350 DIAPERS) Both of of our older boys were in size 3 diapers for the back half of their first year. Baby B is just moving into size 3s and I think he’ll probably be comfortable in these for a good while just like his brothers.
- SIZE 4: 22-37 LBS. (10-16 KGS.) MONTHS 11-12+ 1 LARGE BOX (~200 DIAPERS) I don’t think you really need to stock up per se on size 4s for the first year, but my oldest moved into size 4s just before his first birthday. My middle probably could’ve waited until after his first birthday, but we started using some in month 12 just because we had them on hand. Each of the boys was right around 24 lbs at one year.



In addition to our diaper stock pile, I love to stock pile the baby wipes too. I love the sensitive version in most baby diaper brands because it’s alcohol and paraben free and so easy on the boys’ sensitive skin. There are so many uses for baby wipes and we’re readily using 2 or more at each diaper change, so it only makes sense to stock up on them. Especially because I use them even with our oldest and he’s been potty trained for over 2.5 years!
While stock piling diapers isn’t a necessity, it’s worked out well for us. One of the best things that made it easier to transition from two to three kids was to build an ample diaper stock pile for baby’s first year.
