Query: Good idea but poorly made

I was excited about this product, I bought this one and the one with the zoo animals sound.First it work, but then it began to work only when it wanted...Sometimes one animal work, sometimes 2, sometimes all of them...But it's unpredictable and really frustrated overall!How do you explain to a 19 month old that the puzzle does'n't work all the time.At the end my daughter was not interested in it at all...Too bad!And also the sound of the animals are not really realistic.
