Frankly when I read that the manufacturer recommends this toy from 4 years old, I do not understand. Indeed, this truck was given to my little boy for his 1 year and it's crazy. There are no small parts that can come loose which could be dangerous. So actually, the truck is equipped with several buttons on the cab roof which aim to encourage the child to count or recognize the colors and my boy is too young for that, however it does not prevent the worship listen to short questions and it also has a button that makes the engine noise: what fun! Personally I find this toy really well. This is a basic for boys (like little girls and my 3 year old daughter also plays regularly with his brother's truck). I find the toy very durable and also very cute with its shimmering colors.
