The cake has been eaten and the odour from your pre-party poo has finally dissipated. So as your party is winding down, your little guests are now starting to wonder what’s going to be in their party bag. The party bag says a lot about you as a parent – are you cheap and cheesy, or generous and sophisticated? Well, how about using the party bag to prove your Dadget credentials by giving a hi-tech gift that the kids (and their parents) will be talking about for months to come?

My top party bag tip is to use the appropriately named GoDaddy.com to register a domain name for each of your guests. How cool would you be if every visitor to your party went home with theirname.com registered and paid-up for 12 months together with a free starter web page and e-mail account? You really are the coolest Dadget dad in the world!

If your wallet can’t stretch to the £6 per child for a .com, then you could plump for a .info at only 66 pence per child – what a bargain! Of course, you will always encounter a few snivelling little brats who really wanted a matchbox car and a packet of sweets, but life is full of disappointments.

Now that the games have gone down a treat it’s time for the ceremonial bringing in of the cake, complete with candles. But what if you used your last match to mask the stench of the horrendously smelly poo you had just before your guests arrived?

Step up the iPhone, which has a million and one candle applications to give you that hi-tech virtual glow. Birthday Blow Out (£1.19) provides you with a tasty-looking cake covered in candles. What’s more, you can blow into the iPhone’s microphone and see the candle flames flicker. If your kid blows hard enough then the candles will go out, and your iPhone will be drenched in spit.

For more kid-friendly iPhone fire gadgets you can also try Flametastic (59p). Here you can display flames from a candle, match, gas source or blow torch. It’s a very safe way to provide gentle light at your child’s bedside, and you can also use it while you make sweet love to your wife/mistress. Bonus.

So you’ve had success with your electronic invites and now your house is full of screaming children vomiting peanut butter sandwiches into your DVD player’s disc-tray. Time to settle them all down for a few board games.

But why punish them with complex mental arithmetic when adding up the scores? Sure, you could be generous and give them a calculator to use, but you’d still need pen and paper to write it all down.

So whip out your iPhone and solve the problem by using the EZ Score app. You can keep track of everyone’s score very easily, even having a photo next to each child’s name. For 59 pence (or free for the Lite version that is limited to 3 players) you have become the cool dad with the iPhone who didn’t make his kids practice mathematics when they were supposed to be having fun. Dadgetastic.

I’m not a fan of party-planning myself, possibly linked to a dream I once had involving Margaret Thatcher and a bowl of car keys, but I feel that a few good Dadgets will see me through anything. Having children means that you’ll end up arranging countless parties, so what are the Dadgets to look out for?

Let’s start with the invitations. Why waste money and rainforests on paper invites when you can plan the whole shindig online for free? There is a wide range of party planning web sites that will allow you to send e-invites to your event and then monitor the RSVPs as they come rolling in electronically.

Evite is possibly the most famous such web site, but their homepage is too busy for my liking and they have a bad reputation for saturating the whole experience with too many advertisements. I liked the look of PurpleTrail as an elegant and feature-packed solution, until I discovered that they don’t allow you to do anything from a Mac web browser – tut, tut, tut.

So my choice of online invite services has to be pingg due to its simple interface and support for all web browsers. Yes, it does have advertisements, but they are not very intrusive, and the way that you can integrate photos, web links and even YouTube videos is pretty cool. I’m currently helping my wife to plan Henry’s Christening and pingg is definitely my tool of choice.
