How to help kids to hold their cards in their hands ?
Patience is the only thing I can think of, with my kids (aged 6) I started by fanning them out and place them in their hands finished, lately they collect them and take a grip and I only fan them out for them.

As an alternative just buy a couple of Playing Card Holders and worry about it later on :)


These should be available a little everywhere but the image is taken from: Peta (first image of them I found on google image search)
