I took 3 months leave (wish it was more) when my daughter was born, spread out through the year a month at a time. I loved each month for different reasons and I know each month helped me understand what my wife was dealing with better and the slog of looking after a baby as well as the fun bits, and it helped her understand me better too - she really missed our daughter when she did a month's work and saw how going to work every day wasn't such great a holiday from childcare as she thought!
