My baby will only nap latched on

Al

In need of some advice on what to do.. my almost 4 month old has suddenly decided naps suck and he will only nap if he’s attached to my nipple the whole time.. I kid you not, he’s been attached to me over an hour.. anyway, I’ve tried multiple types of pacifiers and nothing is working.. I don’t mind laying in bed with him during naps but I don’t want to be fully attached by the nipple all the time.. what can I do here
