Girls, who bought electric bassinets, how did your baby react to it? I bought a bassinet and my son fell asleep on it after three minutes, then started crying loudly. I was scared that he got shocked. I put my hand slightly pressing and sat for ten minutes and nothing. I put my hand under the child again and cried. It wasn't like he got shocked, but he is afraid of this bassinet. I think to be sure, I turned off the bassinet and laid the baby down again and cried.?
