We were in Bali in August and I just wanted to recommend a lovely driver for anyone who is traveling in bali soon :O)
His Name is Putu and he is a great driver... I couldn't recommend a more honest, lovely guy who will show you the sights, tell you anything you might want to ever know about Bali, help you with shopping (even tell you the prices you should be aiming for) and he is absolutley fun to spend the day with :O). He has very reasonable rates and when you consider that he doesn't take commission from the shops then it can work out more in your favour.
We travelled with our 3 yr old and 6month old and left him with our Infant car seat so he has that if you need one and dont want to lug one over with you.
He has a 3yr old himself so he is great with kids!
His website address is

Go and check it out... I gaurantee you wont be disappointed- oh, and he knows the way to the birthing centre in Ubud now if you want to drop off donations :O)
