I'm taking 6 months away from my day job to look after my son, Archie, who is now 8 months old. I thought it might be interesting to share my experiences.

So, we were back at the V&A this weekend for their Digital Design Weekend event. There was a promise of robots to lure me there - I've always loved robots and try to take every opportunity to hail our future overloards. Sadly the event was a bit frustrating as the exhibits were scattered somewhat randomly around the museum and there was very little signage to help. My robot hailing was ultimately limited to the Dr Who-esque 'Diamandini' (above), whose principal special power seemed to be making people uncomfortable by invading their personal space (I think Azimov must have left that one off the list). While we searched in vain for more robots, I was interested to see the V&A have added some Japanese streetwear, such as Gothic and Punk Lolitas to their fashion section. They were weirdly familar from years of playing JRPGs.

In truth our visit was curtailed by more prosaic, baby-centred matters as Archie suffered a Tewksebury and we decided to cut the trip short. Now, before you Google the word and get confused (or worried for his welfare), I should probably explain that my family, possibly like many others, has a history of coining and using new words or phrases. These phrases never go beyond the family, but do become permanent extensions to the dictionary - a kind of family slang. For example, as a kid, the phrase 'Kung Fu Pudding' came to mean sausage, mash and beans all mixed up into a single mess on the plate. Nonsense to everyone else but meaningful to us.

So, what about this Tewkesbury? Those with a decent knowledge of British geography may be aware that Tewkesbury is a town in the west of England, just north of Gloucester. We'd been having a conversation about it as a possible location for my mum's 70th birthday and, by coincidence, the very next day it hit the news as torrential rain put the town at high risk of flooding (major flooding had previously hit the town in 2007), so when, later that day, Archie's nappy had a little leak I said that he's had a 'Tewkesbury'. We've been using the term, the abbreviation 'Tewkes' and variants ever since.

So, the exhibition was a bit disappointing and Archie had a Major Tewkes, requiring a full outfit change in a baby changing room with a bad lock and another mother determined to make it known that she also needed the facilities (I think she might have had the dreaded 'Brown-Tewkes' to deal with, but what can you do?) We treated it as a sign from the flying spaghetti monster and headed home.

Anyone else have any good examples of 'family slang'? Pop 'em in the comments.
