8 month old having trouble sleeping

My son is 8 months old. Recently he has been having trouble sleeping. He eats dinner with us at 6. Then from 6:30-7 he gets a bath then from 7-7:30 he gets a massage he gets read a book and he breast feeds then he is in bed from anywhere from 7:30-8. He had no problem going to bed but for some reason he wakes up at midnight then I give him his pacifier or pull the blankets on him then again between 2-3am but this time he is awake awake and wants to play and the only way I can get him to go back to sleep is if I feed him. Then he sleeps until 7:30. I don't want to keep feeding him at 2/3am what can I do to break this habit? Before 8 months he slept through the night great I'm not sure what changed.
