These crochet bonding squares are a thoughtful gift for any mom who has a tiny baby in a neo-natal unit. The simple squares are easy to crochet, and at just 5″ x 5″ they work up very quickly.

What are bonding squares?

Bonding squares are simple knit or crochet squares, measuring about 5″ x 5″ / 12.5cm x 12.5cm. They are knitted or crocheted in pairs. One is placed with a premature baby and the other stays with mom. After 12 or so hours, the squares are swapped, so that baby is comforted by mom’s scent even though she can’t be with her little baby all the time.

I only recently learned about the concept of bonding squares, as part of the Preemie Crochet Challenge organized by Sunflower Cottage Crochet. It is such a lovely idea, and as a mom myself, I can only imagine how it hard it must be for new parents who have a tiny baby who they can’t pick up and cuddle.

Yarn for Preemie crochet projects

As with any item intended for tiny babies, you will want to choose a very soft yarn for these bonding squares. Acrylic yarn, or other non-wool blend, are good choices. You will want to make sure that the yarn is machine washable!

In terms of yarn weight, #2/Fine or #3/Lightweight yarns are a good choice as heavier yarns could cause little babies to overheat.

I used Stylecraft Special for Babies DK for my bonding squares. Other great choices would be Paintbox Yarns Baby DK, which comes in a great selection of colors (and not just pastels!), or Lion Brand Babysoft.

These little bonding squares are really simple to crochet – if you know how to sc (single crochet) and dc (double crochet), you’ll have crocheted a pair before you know it. I decided to add a simple single crochet border to give the squares a more finished look.
