Dear Doctor, My baby is one and half months old. I had put her in the cradle (cloth cradle which swings vertically). While swinging the cradle suddenly baby's head came up to little height (around 3 to 4 inches) and went back to the cradle cloth. Suddenly baby closed her eyes for two seconds (like baby is scared or she had a small jerk) and after two seconds baby is normal now. Will something happened to baby. I am worried a lot as in Google its mentioned like head shaking and all. Please reply me asap. Will it have any effects in later stages. Thanks
