LEGO is one of toys that I've been anticipating The Boy playing with for a few years; he likes creative toys and producing something, plus it's a great, traditional toy which is so versatile. However, when other two year olds were busy with large construction blocks and building garages and houses, he would merely turn to another toy disinterested in LEGO's potential. Who knew that it would only take last year's trip to the Mecca of all 'blockheads' everywhere (LEGOLand) to ignite his curiosity in Duplo, and since then LEGO. We last went in October half-term and I ended up smuggling two boxes of the stuff (for his Christmas presents) back to the car, wrapped in my coat so he couldn't see what they were, "No darling, mummy's just hot. That's why I've taken my coat off"!"

Last week I received a parcel which sent The Boy into raptures of delight! To celebrate their new promotion, Shell and their technical partner Ferrari have teamed up with LEGO to produce six exclusive models. In the range there are; Scuderia Ferrari truck, Ferrari F40, Ferrari 150° Italia, Ferrari 458 Italia, Ferrari FXX, and a Ferrari 250 GT Berinetta. Each one is powered by revolutionary micro-propulsion engines, the smallest ever pull back engine built by LEGO. And we were very kindly sent one of each model, along with a storage box and instructions on how to race them.

This is the first piece of proper LEGO that The Boy has played with, and we had great fun making it together; me deciphering and translating the plans into minute steps for The Boy, and him almost putting them in the right place each time. However, we got there in the end (despite daddy coming and taking over completely with one car) and decided to test them out to see which of the cars was the better at the jump-ramp we positioned in his tuff-spot.

I need to warn you that this video was the last one I could handle recording; it was the eleventh 'take' and we'd gone from mad chatter to doing it in silence, via him getting completely confused and doing the cars backwards. By this time, I was delirious with hysteria (the mic on my phone went weird at one point), he'd turned into the biggest over-actor of them all (no Oscar awards ceremony for us in the future) and we were cold.

In order to get your hands on these models for £1.49 each, fill up with £30 of Shell V-Power Nitro+ Unleaded or Diesel at any Shell garage between now and 8th January 2014, the cars are available while stocks last. LEGO and Shell are also encouraging you to get involved by videoing one of four exciting challenges (found here), and uploading and sharing it via twitter, Instagram or Youtube using the hashtag #LegoChallenge. There are a great selection of prizes for the best entries. More information can be found here.

We were sent the above products for the purpose of this promotion.
