Change. It happened to me about eight weeks ago when my first child was born.
Five days later, my wife and I were both back at work - and taking care of our son.
If it was going to work, we had to become more efficient, save time and work differently.
We have managed the multitasking - so far - by making good use of technology and innovations that just a few years ago would not have been available to us.
I use ultrafast broadband, Skype and FaceTime to stay in touch with the office, staff and clients, so there is no need for me to travel into town every day.
