In coordinate representation the coherent state of oscillator is the wave packet with shape similar to the general state. If its width oscillated they say that this is the squeezed state. The time evolution of such packet is given by an equation of the Riccati type. It is shown that the packet with the shape similar to the n-state of oscillator described by this equation to. That analitically integrated for attractive and repulsive potentials. Gidrodynamics analogy is applied to analyse such type of wave packet.
