At what age did you first hear your baby’s giggles? Mine was when she was 3mons old :)

I first heard it when she was about 2 months old. We were changing her on the bed and I went to switch off the ceiling fan afraid she might catch a cold. As the fan is slowing down, she could see the blades going in circles and that was when she started giggling. It was the cutest sound ever and I even managed to get it on video.
