Hi and welcome to the forum

If it were me, I would feed and put back to sleep, especially if he wakes hourly when you don't feed...that would indicate to me that its true hunger. If he was waking every hour and needed a feed to get back to sleep, that would be a different story. The book is just a guide and babies are all different. Dd1 needed a feed until 9 months, dd2 until 12months and dd3 started sleeping through without a dream feed around 4months BUT she still woke some nights up to 2 times (around 11ish and early morning) and I would feed her at both times and just because she slept through one night, wouldn't mean she would sleep through the next. That was ok with me because I knew it wasn't a prop issue and she emptied the breast and was hungry. She started sleeping through more and more between 4months and 7 months (again, some nights waking for a feed) and recently (about a month ago) started sleeping through consistently.
So follow your babies cue and if he's hungry, feed him
