Haven't read all the posts.I would make a video/DVD of yourself,read some children's stories on it(I think that would be lovely for your DD to be able to hear you reading a story to her)If it was me I'd do lots of different stories for different ages as she grows up.
You could record you reading favorite poems.
For when she's older I'd record myself talking about what it was like when I was growing up,about my children's grandparents and aunties and uncles.What I did on the weekend,who my friends were,what my favorite sweets were,how much pocket money I got,what I spent it on,what music I listened to,about school and any hobbies I had.
I have 5DC and as they've got older these are all things they've wanted to know about me and my life.
I'd buy a gift for every birthday she'll have and wrap it.Write a tag and attach it with a special little message on.Put her age for each birthday for each present to make sure she gets them in order.
Have lots of pictures taken of you together and put them into albums for her so she can look at them when she wants.
Get someone to record you together when your playing,out and about,when you just lazing around and having a cuddle together.It will be a real connection something tangible for her.
If someone has any old report cards,pictures you did as a child,stories,exam results ect I'd put them all into a box that she can keep and look at when she's older when ever she wants to.
If it was me,I know this will be one of the hardest parts but I would write a letter to her for her wedding day just in case,if she does get married when she's older I think it would mean the world to her.
It's awful and completely unfair what your having to go through.I hope you get all the support you need and that people listen to you and follow your lead.I'll be praying for you.xx
