Present from baby to sibling?

[youlemming]

Trying to think of something to get my DD whose 5 from her soon to be new sister.
Want it to be meaningful but something she will actually use, so not sure which way to go, a toy of some sort seems too normal but a keepsake not fun for a 5yr old.

Any suggestions?

Thanks Scot I've ordered that book. I'll decide about a present nearer the time. As another poster mentioned, a little bag of chocolate buttons would probably go down better than anything else!
