I tried the product in the first electric crib, it tried to understand the sound before going to sleep and it was not very effective in the first mode. I especially observed calming in the second mode. It stopped moving its legs and went into sleep mode. Normally, it would not stay in the electric crib for long and would not sleep, but it calmed down.

When I used the product in a normal crib, I actually noticed a difference. My child, who could not sleep because of gas, fell asleep more calmly. Also, since the sound of the device had a white noise effect, it made falling asleep faster. I constantly used mode 2 while he was sleeping. He fell asleep easily as if he was always in my arms.
