A cozy, practical baby onesie available in sizes 1-18) months. It’s designed with a zipper because, let’s be honest, dealing with a thousand buttons is the last thing you need when the baby is overtired. Warm, soft, and complete with a snug hood, it keeps your little one perfectly insulated on those chilly days.

The onesie is knitted seamlessly from the top down using Isager Soft from @isageryarn—a beautifully gentle yarn perfect for baby knits. The pattern is written with clarity in mind, with every step and row clearly outlined to make the process as smooth as possible.

Size guide:
Choose the size that corresponds to your baby’s current age, but compare the garment’s measurements with your baby. As long as your baby is not between two sizes, you can confidently choose the size that matches the age your baby will be when the garment is finished. The fabric naturally stretches with the baby, and the ribbing is knitted in double length so it can easily be folded up or down as needed.
