My son is 2 and loves this book/ song! He is singing it all of the time. The picture are so colorful and fun. I highly recommend this book for kids under 6.My grandson loves this book.One thing I Do NOT like is the author has the sheep say ‘mah, mah, mah’.Enjoyable for all the family. My three children, aged 2, 4 & 6 all loved it. The boppy background music on the cd makes the story even better. Great education with animal names and sounds as well as counting. Watching my children enjoy a book so much gives me extreme pleasure and joy. They just want to hear it over and over again. My eldest knows the words off by heart and my four year old is not far off it either. So when the cd is playing the third part, which is just the background music with no author reading it, my children say the words themselves, which is great for their memory too. Fantasic book. Don't know what else to say, except that I highly recommend it. I wish I had a video review for you to see, as my 2 year old has a toy red tractor ride on, and he scoots around the house singing "moo moo moo, it's a very busy day". It is so cute. Great Book!I HIGHLY recommend this book series to people who have autistic children. We had trouble with socializing, with speaking, and what’s great is this book comes with a CD, so the more we played it, with the pictures, the more eye contact we got, the more socializing. There’s also some cartoons of the book on YouTube that our kid loves. I highly recommend for kids on the spectrum.We got this book from the library a few years ago for our now 5 year old daughter, who loved it. We decided to purchase it for our 11 month old son. Now the whole family enjoys listening to the CD while we read along. FYI: I wanted to know what was actually on the audio CD but couldn't ever find it listed. The tracks are:1. A 1 minute music instrumental and author introduction2. The author singing the book's text along with the music3. The same as track 2, without the author's singing4. A short music instrumental, similar to track 1.I found this book as a video on YouTube and my 21 month old daughter, my husband and I all loved it so much we bought the book! We have had this book for about 2 1/2 weeks now and I read it at least 4 times everyday and whenever we see a tractor we break out in the song. Such a great little song/story with sweet pictures and at the end it shows different types of tractors/machines used on the farm as well as many crops. We love this book and will be buying more for gifts as well as other titles from the author/illustrator :o)My son loves the song/book. We've had it for over a year and the DVD still plays after hearing the song on repeat (#3 on the DVD) millions of times!!!My class is obsessed with this fun book! Definitely a must buy!I know this song by heart. I got this for my son when he was less than a year and it's been his favourite for the past 6 months. At the beginning we would have to read it and re-read it immediately.Definitely one of his favourites still.The illustrations are also nice and we played 'where are the rabbits' for a while as there are rabbits hidden. He also loves the combine harvester.A definite 5-starsAs with all Barefoot Books this is excellent. The accompanying CD means that the children learn the song quickly and easily whilst also learning to count. I have used this book as an entire maths topic and the children made a great display of the animals in the trailer along with the relevant numerals. Plus it's a really catchy song that stays in the children's heads for ages (and yours!!))One of my daughter's favourite books and it's even better with the CD. You get both a 'karaoke' version and full song version, which means you can listen to the original song then sing along. The only slightly disappointing thing about this book was that it was not hardback but was a slightly more robust soft back. Would be nice to have a hardback version of this book as it gets quite a bit of use!Discovered this story on a you tube video and the child I look after loved it from then. It has been a great purchase. Reading the book and listening to the song at the same time is great fun. The CD is great as you can play it in the car or anywhere. The fact that it encourages counting is just an added bonus. A book that we read over and over again. A firm favourite.My son loves these books with DVD. He autistic and loves you to interact with him.
