Cielo Preemie Bonding Squares Crochet Pattern {Free}

Preemie bonding squares are a great way for mom and baby to feel connected. You can quickly make a set for a premature baby to donate to your local hospital’s NICU unit, or to moms who has just brought a preemie home from the hospital.

You can also make the Cielo Preemie Security Blanket to complete this as a gift set.

Note: Please make sure you check with your local NICU department to see if they are accepting bonding square and/or other preemie items, and what their specific regulations might be.
