It's a bugger all right!

Have you tried a piece of sticky tape? Just cut a piece off and join the two ends together to form a loop with the sticky bit outside. Apparently bubs will be so in awe at how it sticks to their fingers they will stop whatever they are doing. This was some advice from a friend of mine which I never tried out with Jack.

Other than that, anything to look at or play with, like books, balls, tubes of cream, anything at all that will give you a couple of minutes grace.
