Struggling with words for this condolence card

[mckenzie]

A lovely lady who works with DH, who I have met a few times, lost her baby during the delivery.
We don't know any more details.
I'd like to send a card but I'm really struggling for the right words to use.
There can be no memories to enjoy.
any tips please really gratefully received. I cannot begin to imagine what she and her DH are going through and I don't want to add to their heartbreak and upset by sending a card with thoughtless or hurtful words.

TIA

Sadly I've been in the same situation. Could you write something along the lines of that there were no words to express our sorrow for them and that they're in your thoughts and hope they find comfort in the support of friends and family. We made a small donation to a related charity and wrote in the card that we hoped they got the guidance and care that they may need in the coming weeks and months. Hope that helps

perfect. thank you so much
