Definitely not as good and effective as the same company's rattle for a 3.5-month-old baby. The legs of this hanging toy make an interesting sound that the baby likes, but they are still out of reach for the baby to play with, so someone has to shake them. Also, a major negative is that the green part that hangs the toy looks like a big safety pin, and if the baby pulls it a little, it comes off and can fall on his face! We experienced this with the egg. It slips relatively easily. On the positive side, there is a mirror under one leg, which the baby liked a lot when I showed it to him, during the car ride and it kept him occupied. However, he quickly lost interest in it. Another negative is that the doll has very small eyes that cannot be seen from below, so the baby cannot recognize its face.

The best thing I have bought for the baby. He plays with it all the time, it has a loud sound and he likes it, I can take it everywhere with me. (I have given it as a gift 4 times and they all say the best things about it). Number one toy for me
