Bostock has started three of the last four games for the Robins, his best run in the side since sealing a temporary switch to the County Ground from Tottenham in August.
The 20-year-old was left out of the squad for nine successive games earlier in the season, but says he has rediscovered his enthusiasm for the game after earning a first-team recall.
He told the Swindon Advertiser: "I just feel like a kid again. I look forward to Saturdays.
"At Tottenham I was just training, training, training and not featuring but now I'm training throughout the week and to be involved on Saturday is fantastic.
"At the moment, I'm on a little bit of a high because I'm playing and enjoying my football."
