'Dear Sarah,
I just wanted to share a few words to let you know how thankful we are for all of your help with the arrival of Marnie. First of all, thank you for helping us at the last minute before her birth. It was so reassuring once I knew you were taking on my care. Thank you for being by my side before, during and after her birth, for making me feel safe and for your kindness every step of the way''
