Hi Pete - meant to respond to this thread t'other day, so just throwing in another suggestion.
Memory book. With the photos and her keepsakes in (e.g. hospital bracelet), dates of first tooth, first stand up, family occasions etc. There are some beautiful ones out there which come with the sleeves - photos are protected, keepsakes are kept safe.
Last year, my best friend got breast cancer (she's survived) and I made her a memory book before she went in for surgery... <can post you pics if that would explain it a little better, just let me know as she's coming down from Essex for this Bank Holiday and I can ask her to bring it down to photograph>
So, I don't know if you've ever used Picasa - I used it for years before going into PS5 and tbh, for a quick upload, I still prefer Picasa.
It has the collage facility and, IMO, it's brilliant - you can change the shots around to whichever you want - some larger, uniform, ones mosaic'd around the outside of a larger shot etc. I know most here prolly wouldn't use Picasa, but for a free download and ease of use, it's great.
The Memory Book is something I know Charlie will treasure for the rest of her life - pics of when we were wee kids, special times, family, pets and of course, our kids growing up together.
If you did something along those lines, it's special for you, Claudia and your family... and a keepsake for when she's older which can be given to her later in life. It's also tangible... very different to looking at a screen... you'd be surprised how many times your hands would brush across those photos as you and family look through it.
Anyhoo - just a thought... not everyone's cuppa tea - but sure works for me and mine.
