Having had the pleasure of doing both in recent months, I've come to realise how launching a startup and having a baby share a lot in common. No sleep, no cash and friends making you feel 'good'...here are eight similarities between the two.
1. You can't choose a name
You spend your commutes making numerous lists on your phone, and after plenty of toing and froing you eventually settle on something that your parents don't like.
2. You read books
You prepare by reading lots of books before quickly realising that the theory is no preparation for the practice. And once it starts, you laugh at the thought of having time to read a book ever again.
3. You have funny 'friends'
You have friends fraying your nerves with funny quips about how the good life is over. You laugh along with them, but inside you're panicking.

4. You see your partner in a new light
You share fun new experiences with someone
you want to blame for everything you're glad is there to calm you down during moments of exhaustion and stress.

5. You have no money
You start to spend too much time in the supermarket trying to work out the most filling combination of the items in their £3 meal deal.

6. You get the animal instinct
You develop a protective instinct that kicks into gear the split second you sense anyone even, possibly, maybe, potentially looking at "your baby" the wrong way. Or not looking at them enough.
7. You don't sleep
8. And you develop massive appreciation for those who've done it before
You suddenly realise just how brilliant the people who've done it before you really are and feel guilty for not giving them the kudos and respect that their efforts deserved.
