I do not know, those who prefer the bird: my husband and our daughter !!! We have the bird at home now for a few weeks, at the beginning he was a bit too heavy for her and if she kept him lying down she let him plop on her face after a while, but now with 5 months is the bird of the full Hit! As soon switched to him, she smiles and even waves his arms as they like to keep it myself. Is also great that he not only flashes and sing when you press the button, but also when she shakes him. The music is not too loud and not tinny like many other toys. Thus, the bird is a fun for our whole family.
