That's pretty rubbish your DH was so careless with the photos. Mine would have been super unpopular. Are there any relatives who have some shots from the early days?( sorry if this has already been asked and answered).
But I'm another who thinks the feet and hand casts, pregnant belly casts and all that are pretty tacky and essentially monetising sentimentality which I think is nasty, so don't feel bad you lack these things and never compare yourself to others, as it's a surefire way to make you feel inadequate which you clearly aren't.
You can still have fun doing hand and feet prints on paper together now, and add to them each year and keep other special things from childhood to look over later.
I also shudder at the term "making memories". It's like " whoops you failed to make enough memories therefore you are rubbish compared to X who has everything publicly displayed on social media or in their home. Those are proper memories, therefore you fail".
How do you make a memory anyway? They just are.
I have food prints of a child of mine that did not survive and they are precious but I would not personally choose to display them. I still have his ashes, which I can't let go , or plant under a tree because we might move again, and I would struggle to leave him behind.
I don't have foot prints etc of my living children, and if I did wouldn't display them. I have a trunk with first clothes worn home from hospital, first lock of hair cut, teeth, first ultrasounds , first favourite toy and little artworks etc , We even took the part of the door frame that had their heights on it from the home we lived in until they were 6/9. Every now and then we go through it all and reminisce. Even the hulking DS 16.
