These set of blocks were bought for my 6 month old daughter. She played with them for about 10 min looking at the vivid colours before moving on and I felt disappointed.
within a few days I realised something and sat down with her .. making the puzzle and showing her .. the Cow ..moo moo ... Then the cats .. meow meow .. and now after about a month .. she adores the blocks and sometimes spends 15min listening to me .. which is a lot for her to stay in one place. She can now identify the meow meow (cat) and quack quack (ducks). These blocks have quite a few different animals and also have numbers to help older children count. One horse, two cows, three sheep's, 4 dogs and so on ..
The soft blocks are absolutely no worry as my little girl crawls / tries to stand up and fall on them. The blocks also make a soft rattling sound however my girl didn't care about it much, nor was excited by the sound.
Right now I am teaching her the animals and sounds... soon they will be used for her to identify the animal and later for her to solve the puzzle herself and finally learn counting. I am confident that with time this will be very useful .. I expect to use this till she is 2-3 year old. Well worth the money.
However, if you want the kid to play by this themselves, buy this for an older kid.
