It was summertime and I was very thirsty. I wanted to drink orange juice very badly, but I did not have any orange juice. Luckily I had an orange tree in my backyard. I picked some good and ripe oranges to juice. In the kitchen, I brought out my electric juicing machine and plugged it in. I washed the outside of each orange to make sure my juice did not get dirty. Then, I cut each orange in half and turned the juicer on. This kind of juicer worked by spinning a plastic piece inside the juicy part of the orange when you held the orange against it. The juicer squished all the orange bits inside the peel and turned it into juice. The juice came out the side of the juicer from a spout and poured into a glass that I had put there before. The juicer was very good at its job, and removed all the seeds from the juice that came out for me. The orange juice was fresh and tasty.

Every night I must put my son to bed. His name is Alex, and we have the same routine we do each and every night. Last night, we started our bedtime routine by taking a bath. Alex played with his bath toys, and splashed around in the bubbles. He then got dried off and put on his pajamas. Last night he wore his favorite pajamas with Lightning McQueen from the movie "Cars". We went into the bathroom and brushed our teeth, Alex used his green Crayola crayon toothbrush, and got his teeth nice and clean. We then read a bedtime story, last night was Goodnight Fish, which was a book he got when he and his grandparents went to visit the aquarium. After that, he got tucked into his crib, with his favorite blanket, and his favorite stuffed animals: a lamb and a penguin. We sang "Twinkle, Twinkle Little Star", and turned off the lights. Like each night, it was a good night. 
Question: who took the child to bed?

The parent.
