Bought it to our daughter when she was 4 months (age 3 months). It was at the beginning much too heavy to hold for our daughter. It was not until the 6th month, they could then hold alone. But even at that time it was sometimes even out of his hand and on his head. That it did so hurt quite a bit. The sun was great, because you can roll it back and forth. Lange has not taken it. Then it was her too boring. Would not buy again.
