Ed, David and Nick - spot the daddies.

Now I can't be alone in noticing that all three party leaders are the fathers of very young children. I'm sure somewhere political commentators are speculating on the effect this will have on key policy areas like child benefit, nursery education and maternity care. All fascinating and relevant to us fellow parents, but the question I'd really like to ask is just how much childcare do this lot do?

On the face of it they all make quite a show of being hands-on parents - Cameron dutifully took his paternity leave as did Nick Clegg (his wife Miriam actually went back to work first) but I'd love to be a fly-on-the-wall and witness the day to day childcare negotiations in their families. Does DC formulate his Question Time strategy pacing the house with Florence at 2am? Is Cleggy pureeing carrots after a hard day of coalition negotiations? Has Ed endured the hell that is soft play? They all seem suspiciously puke /poo /puree free......
