I didn't like looking after the baby

My 13 year old has difficulty with speech (he has Cerebral Palsy) and so it can take some time to gain a picture of his day. We haven't got to the bottom of who pushed him over today or why, but as he doesn't seem bothered by this, we aren't either. What we have learned over the course of the evening though is that he had to look after a baby (an electronic doll if I have understood him correctly) over lunchtime. We managed to learn that this was part of PHSE and that he didn't drop 'her!' Any attempts though to garner what understanding, learning or reflections he had gained from the experience were unsuccessful. I was therefore delighted when, as he was going to bed, he thoughtfully stated,

"I didn't like looking after the baby"
Eager to hear his reflection on parenthood (albeit only a brief simulation) I inquired as to why. His response, "Cos' I wanted to play football!"
