We send photos that are quite obscure - such as our son with his face painted, or in fancy dress, or covered in sand at the seaside. Not very recognisable. We did however send each birth parent a close up photo just as son was placed - so they had a nice large photo to keep and frame if they wanted. After that then we deliberately obscure without refusing to send. We also send the odd picture our son has drawn (he chooses) which I am sure they like to see. The return letters from birth mum say things like - how big he's growing, how happy he looks, how good at drawing he is. Our son also benefits because his birth parents know how well he's doing and that he's happy.
