Knitters and crocheters - come help some babies!

[Bringmewineandcake]

Sharing from a Facebook mums group I’m on -

St Thomas Hospital have run out of bonding squares on their neonatal intensive care unit. Bonding squares are pairs of 5in x 5in knitted or crocheted squares (any colour, design or wool but they need to be washable).
One square is put with the poorly baby and one with the parents and they are swapped over daily. They are crucial for premature or very poorly newborns and parents who are separated at a very stressful time.
Please send to:
Neonatal Unit

I posted this in Chat originally and a lovely poster pointed me in this direction.
Some useful help from another poster -

For reference: double crochet/4mm hook/30 stitch row x 18 rows, plus 2 rows of dc border gives a square about the right size.

Can I just update?
I was about to do some, but St Thomas have tweeted that they have so many offers, that they don't need anymore just at the moment . :)
