whiteandyelloworchid, I have told my grandma story here a couple of times before, so sorry if you have read about it already.
My grandma died two years ago at the grand age of 99. She was the centre of our family, an amazing, hard-working lady, who was just good, that's the best way to desscribe her. Just GOOD all over.
She had 6 children. Her third girl died at 17 days of age, her name was Maria Elena. This was the first half of the 20th century. Babies who died weren't mentioned, they never existed. Her own husband didn't want to talk about Maria Elena and told her off when she had "still not got over that".
But she did not care, my grandma. She went on talking about her and bringing her up in conversation, ender stern looks from my granddad, and awkward looks from guests. I grew up knowing about my auntie Maria Elena. She only had one tiny black-and-white photo of her, you could barely see anything. But it did not matter, because after 70 years, she was still as clear and vivid in her mind as when she was alive. She would describe to me her long, curled eyelashes, and her dark curly hair. When she told people about her death, she would cry every time. And smile every time.
Old age is very respected in my home country, Spain. When she went over 90 years of age, strangers would frequently start conversations with her - she was lucid up to her 99! And every single time someone asked "How many children have you had?", she always said: I had 6 children. And if the person was curious about them, she would tell them about the six of them. In order. Maria Elena was third.
So yes, you can. You can and you will remember your little DS, who will always be your DS1 no matter if you have another 10 children. My grandma could, and had to fight even her husband, and countless other people who just thought "you do not talk about this stuff". But she succeeded, and thanks to her I have a memory of my dear auntie Maria Elena. If you want, your children, grandchildren and great-grandchildren will get to know your DS. Would you like to tell us his name? If you do, l I will keep his name in my heart together with all those names that some other people did not have the luck to get to know. It will be my little treasure and he will share this special place in my mind with Maria Elena, as she will share that space now in your mind, because now you know about her too :)
