I'd buy this hippocampus when I was pregnant with my daughter. it will now be 4 years old and the blanket always accompanies her sweet dreams. it still works perfectly, the batteries do not uses too quickly. the sound is adjustable in position 2. he goes out alone at the end of the melodies, or we must remain on his stomach to support turn it off. The musical mechanism is easily removed thanks to the scratch, in order to proceed to washing. mine is spending tens of times in machine and did not move a hair. for Christmas I will buy one for my 2nd second chip that at 7 months. I highly recommend your children will love it !!!
