I got this for my 5 months old knowing that it was a little early. At 6 months he was in love with this and at almost 7 months he plays with it everyday. Great toy and has many more months to grow with him.

It was one of his first toys and as he's grown (now eight months) he still enjoys it.

Our son was walking at 7 months so it was a struggle for us to find things for him to keep his interest and help him learn as most toys in the 6-12 month range expect your child to be less mobile.  This has been a TERRIFIC toy/aid for him and he pushes it around, rides it, crawls under and over it and even hangs on it.  The construction of the toy is top notch and is VERY durable.  The only con i would give is the tools it came with are a little cheap.  I know my son and he is strong and rough so i tightened all the bolts a little more with my own tools to assure they were 100% tight.

We love this product and look forward to some of the other products the manufacturer offers as our son gets older.

My baby loves this toy, he's 6 months old now and is still as interested in it as he was when he was 2 months old!

I bought this for a co-workers son.  He is almost 6months old and already likes to play with it.  She can't wait until he gets a little older so he can enjoy it more (not just the music).

My son is now about 18 months and he had this toy from birth.  It was not his favorite toy, but it did keep him entertained for a good amount of time -- as the title suggests, it is your average baby toy.  Pretty good selection of sounds and songs.  The rolling device on top with the little balls is a nice touch.  After 18 months of use, I only had to change the battery one time.

The only gripe I had was that the keys got sticky somehow.  They no longer clicked and it was difficult to activate the music with the keys. I don't think I spilled anything on the toy, but I may be wrong.  If you are looking for this style of toy, you will not be disappointed.

I believe it was between 12-14 months that this was by far his most favorite thing in the entire world.  He continued to play with it for several months afterward, just not with as much intensity.  Great purchase!  The motor survived him "sitting" in it while running it too. The batteries lasted only about 6 weeks before dying.... but then again, the poor thing ran probably 2-3 hours a day!  Seriously, BUY THIS!!!!

So I try to have my son play with this when he was 6 months old. He really wasn't intrested in at all. Now he is 9 months and is obsessed with-it. I have to hide it from him if I want to feed him or change his diaper otherwise he screams if it's in sight because he just wants to play with it. He would literally play with this for hours if I let him . I really don't understand why he loves it so much he just grabs the balls shoves them in and they bounce around everywhere and they fly out and he grabs them and repeats the process. Over and over and over again . If you need something to occupy your kid buy this,  it's awesome.

I know that the Amazon description says that this is for babies 3 months to 2 years, but I just had to buy this early after I read all of the great reviews.  When it arrived, I attached it to the activity gym (I uploaded a photo of it if you are interested in seeing how I did this).  My baby boy, Benjamin, immediately grabbed it.  He was only 6 weeks old at the time, so I am sure that it was just a coincidence, but it made me feel bad that I had not offered him toys at a level he could reach before this.  Throughout that first day, he became fascinated with the toy.  He quickly learned how to grab (even though his depth perception is still off) and I believe that this toy helped him develop his "grabbing skills" faster than if I had not purchased this toy.  I am sure that this toy is going to get a lot of use from my baby boy.  He has now decided that it is more fun to kick it than to grab it.

Personally, I believe that this toy should have a lower age recommendation.  He was only half way there and I know I could have given it to him sooner.

6 months later, my 1 year old still finds new ways to play with this set. There are so many ways to stack, sort, click, and make different size balls out of this toy. She loves it, and still seeks it out to play with it daily.

at 4 months old.  But when he turned 6 months, he started playing with it a lot more.  I'm surprised that he likes it so much.

I thought my son would like to bang on this because he loves banging in general.  I bought it for him when he was 6 months.  He pretty much ignored it until the past week or two (now 8 mos).  He is not using it as a drum, though, he puts it on its side and rolls it and it makes noise (he is now crawling everywhere).  Still not his favorite, but keeps him busy for 5 minutes here and there.

I have a six month old and he loves this toy, there are a lot of things to play with and the music is actually not totally annoying like other toys.  The only thing with this is the toy moves very easily, almost too easily, my baby moves it and he almost fell flat on this face because it pushes with no resistance whatsoever.

My baby is in love with this toy.  It took until he was 3 months to start hitting the cow hard enough to spin him around.  He also enjoys spinning the ladybug.  We love the songs as well.  I attach it to his carseat and his crib.

We started handing this "book" to our son when he was 4-6 weeks old, and he enjoyed it from the beginning.  Now at six months, he still grabs at it whenever it's offered.  For a small, compact toy, it offers lots of sound, sight, and touch stimuli, and it's well worth having. I only wish the elephant noise-maker was a little louder and removable so we could put the book in the wash.

This is a great toy!  Got it for my son's first Christmas when he was 7 months, he loved it then and has grown with him developmentally since.  He now has the ability to place the pieces in the holes (not always the right ones, but that's just fine :) and hasn't lost interest in it at all.  I would buy it again if for some reason it broke and would suggest it to all.
