Before the end of the cold weather and start the longed-for spring, I wanted to share with you this tutorial and pattern of a knitted onesie that I think is an ideal option to keep a warm baby in his first days (and the rest of his diaper stage, of course).
When I was pregnant, someone recommended that the best bodies for the baby were those that closed to the side without having to stick their heads in a hole, and when I had to dress my baby for the first time I understood the reason for that recommendation. They are so tiny and delicate that you probably do not know how to lift their head and put it through the hole of a neck at the same time, especially the first-time moms. For this reason, the garments that are open over the front of the baby become the best ally for the first weeks, since it is enough to open the garment, put the baby on top, close it and ready!
As you can see, this knitted baby onesie meets all the requirements!
Warm and comfortable as can be, this Knitted Baby Onesie will be a delightful gift for anyone expecting a baby!

Materials to make the Knitted Onesie
The needed materials to make our hand Knitted Onesie are:
- 3 balls of 50 grams of yarn for 4 mm needles. I chose Drops Merino Estra Fine Uni Colour in the color- light greyish green-it knits beautifully and the finish is even, light and very soft, ideal for baby garments.
- 4 mm needles. It can be knitted with either straight or circular needles . I’ve used circular needles because, for me, it’s more comfortable, but I use them as if they were straight turning it around every time I finish a row
- 8 wood buttons that give that “natural” touch to the newborn knitted onesie.
19 stitches x 40 rows in Garter Stitch
How to knit a baby knitted onesie
1. Knit the body of the onesie
We will begin knitting our baby onesie by the neck, for this, we must cast on 46 stitches and knit 6 rows in garter stitch. I usually like to slip the first stitch because I like how it looks and it makes it easier for me to seam the work.
From here, we will start with the increases to go on forming the front, the sleeves, and the back of the knitted onesie. In this way, we will knit 7 stitches, 1 increase, 1 stitch, 1 increase, 9 stitches, 1 increase, 1 stitch, 1 increase, 10 stitches, 1 increase, 1 stitch, 1 increase, 9 stitches, 1 increase, 1 stitch, 1 increase, 7 stitches.
In the image below I show you how to make these increases:
In the next row, we will start by making a buttonhole, which we must repeat every 20 rows. To do this we will follow the following steps: Knit two stitches, yarn over, knit two stitches together and knit the remaining of the stitches as usual.
We will continue knitting our knitted baby onesie alternating a row of increases with a row where we knit all the stitches. You must keep in mind that as you increase one stitch on each side of the middle stitch, if the row with increases is 7-9-10-9-7, the next row will be 8-11-12-11-8, 9-13-14-13-9, 10-15-16-15-10… and so on until you have increased to 19-33-34-33-19.
Once all the increases have been made, we will separate the stitches of the sleeves from those of the front and back that we will knit at the same time. To separate the stitches of the sleeves from the body, we must knit 21 stitches for the front (to the 19 we must add the increase and the middle stitch) place the 35 stitches on a stitch holder or waste yarn, knit 38 stitches for the back, place 35 stitches on a stitch holder and knit the remaining 21. In this way, we must have 80 stitches in our needle ready to continue knitting.
We knit these 80 stitches for a total of 54 rows, we must keep in mind that like the previous part, in which we made two buttonholes, in this part of the knitted onesie, we must also make two buttonholes (row 46 and row 66.)
Once we have the desired length, in row 87, we will have to bind off 15 stitches, knit 50 stitches and bind off the remaining 15 stitches. Do not be afraid of cutting the yarn at this point and weave in the ends with a tapestry needle.
2. Knit the section for the diaper cover
It will be here where we will begin to knit the back area of the diaper cover decreasing a stitch in the beginning and at the end of each odd row. This way, at the beginning of a row we will knit two stitches and pass one stitch over the other (1 decrease) and knit as usual until there are two stitches remaining that we will knit together to make another decrease. The next row we will knit as usual. We will continue making two decreases every other row until we have 16 middle stitches.
Once we made the decreases, we must follow the same scheme of alternating rows to make increases until we have 38 stitches.
Keep in mind that to for the edge to be even you should first knit a stitch and then make the increase, knit as usual until there is one stitch left, make an increase and knit the last stitch.
To finish the part of the diaper cover of our knitted onesie, we will continue knitting a row of buttonholes (row 145), you must remember that this row is somewhat different to the other buttonhole rows, since it has two buttonholes, one at the beginning of the row and another one at the end; We knit two stitches, yarn over, knit two stitches together, knit 31 stitches, yarn over, knit 2 stitches together, knit the last stitch.
Next, we will to knit 20 rows as usual before the next and last buttonhole row, in which we must make three buttonholes in the following way: We knit 2 stitches, yarn over, knit 2 stitches together, knit 15 stitches, yarn over, knit 2 stitches together, knit 14 stitches, yarn over, knit two stitches together, knit the last stitch.
To finish this part, we knit 3 more rows, bind off all the stitches, cut the yarn leaving a tail and weave in the ends.
3. Knit the onesie sleeves
Cheer up that there is a little left to do! To finish our baby knitted onesie, we just have to knit the sleeves. We must place the stitches that we have on hold onto our needles. If you do not want to complicate much, you can knit all the stitches without decreases until you have reach the length of 15 centimeters. If you prefer that the sleeve is narrowed toward the fist, you will need to make a decrease at the beginning and at the end of every 7 rows.
By the way, if you know how to knit in the round with circular needles, you can make them seamlessly, for the tutorial I prefer to show them this way since it is easily accessible to everyone.
To finish, all we must do is sew on our precious wood buttons.
All the instructions os this free knitted onesie pattern are due for a size 0-1 month, but the good news is that it is a very easy pattern to adapt to different sizes or thickness of wool, yarn or needles. For this, I recommend that you look at this tutorial where I show you how to calculate the stitches to adapt a knitting pattern, and do it precisely by reference to a pattern that starts by knitting the neck with raglan sleeves, like this pattern.
What would you think of finishing the set with these matching booties? I think it would be a perfect gift for a newborn that leaves no-one unmoved!
If you like this type of booties, you can find the step by step tutorial and pattern in this link. It is a simple pattern and very easy to knit, for which you will only need to know how to knit garter stitch and make decreases…so versatile that you can make a lot of different kinds!
