All new Dads know the drill. Any would-be or wannabe Dads might as well get with the program, too, because it will creep up before you know what’s hit you.

I’m talking about the ‘Dad effect’, the gradual phenomenon that takes you from punchy to paunchy, from smooth to slovenly and from expectant to exasperated in the space of a few short months.

Its entirely natural given the accumulated lack of sleep and complete disruption to a lifestyle that previously seemed to footloose and fancy free. Your amazing little bundle of joy cares not for your training schedule, your early starts for work and the latest series on HBO.

As a consequence your waistline slowly expands, your jeans sink a little lower around your waist and your stubble starts to become more beard-like by the day.

It needn’t be like this, however. There are a number of small steps you can take to arrest this decline and get your mojo back post-baby.

Heck, if you can tick enough of these off, then you might even find yourself having sex again. Well, maybe.
