alternative to breast as soothing method

My son is EBF and just turned 4 months today. He doesn't get bottle fed and he hates pacifiers. I've tried many kinds. He's currently experiencing the 4 mo sleep regression and he wakes up often and won't go back to sleep without being put on the breast. I don't think he's hungry cause sometimes it's only an hour. Does anyone have any suggestions on how to get him back to sleep without offering him a boob and without letting him cry it out.
