As a 1st birthday gift you shouldn't buy them loads of gifts, which they can't take in yet or appreciate the way one does when you're older. No, write them each a letter with thoughts about them and their future life and maybe a story which connects you to them, that they'll get when they turn 18. And the letters should be sealed. Only the girls are allowed to open them on their birthday. Just imagine reading words from the past, meant for the future in a changed world. Maybe some of the authors aren't alive anymore. Those letters will become even more valuable for the girls. Reading personal words from someone loved, but lost. 

I really like the idea and I'll ask for letters that is for sure!
