I've been having the strangest fantasies ...

Recently, I've been having the strangest fantasies ...

1) A life-size cardboard cut out of myself with a tape recording of my voice cooing, chatting nonsense and singing nursery ryhmes (painful listening to anyone but W - actually come to think of it, maybe it's not good listening experience for him either!)
2) A hologram like the one on Star Wars that R2D2 has in his memory banks of Princess Leia, although I'll need a new script for that one and I'm not sure about that hair do either
3) Time travel - possibly a little far-fetched even for fantasy and I'm not sure where the science has got to since I read that Einstein's Theory of Relativity has come in for some stick recently

Now that he's a bit older and has worked out that he isn't going to starve, he's looking for ongoing entertainment. It's like watching a real life experiment on Maslow's Hierarchy of Needs! So, how on earth do you satisfy a 4 month old's needs for social engagement, learning and development whilst preserving your own sanity and getting some work done? Can you teach babies to entertain themselves or is that a character trait that they are born with? Don't get me wrong, I'm not wanting to abandon him to his own devices all day every day, but how do you teach children to play happily on their own as well as with others? If I can nail that, then I will be able to stop dreaming about 1), 2) and 3) above and get some more work done!
