I have put every single photo from when I was born of myself, sister, mum and dad and aunts and uncles and cousins into photograph albums. Then when I met my husband to be, I put all those photos in too plus baby photos of our children and when they were growing up.
Now when they send me photos to my phone, I download them and print them off and add them to the albums. I have many large albums and from the day I was born those photos tell the story of my life with my sister and parents all the way to 2024 and our grandchildren get them out asking who is this and who is that and it is fantastic to tell them that this is your great grandparents, grandparents, uncles, Aunts, cousins etc. etc. because they never met them as they had died before we were married. It is wonderful to see just who our grandchildren look like and they say, look, he/she looks like me.
I have saved every photo from Moonpig and other companies like them with photos of our family and they are all in albums and dated.
It is surprising how many times our sons ask me to send them a picture of the photos of them taken in the past. Every pet and car we have ever had is in the album. Our grandchildrens photos from being babies are in there and I honestly wish I had saved all the clothes I used to wear from the 1960's.
