I started to put my back into it, sending the Little Boom further and further into the sky with each push.

I have a unforgettable memory with this - When my son was 4 years old, I did the same. He was not fearful, but then he slipped out of the swing and fell at another place with the head bang , bleed so severe that I had to put a cloth and just hold tight, and still his dress got soaked in blood. We rushed him to hospital , got few stitches and then also did the MRI of brain, as the doctor advised since he was vomiting. Thankful to God, he was fine. Also, had he just went a little high, it would have been horrific.
