Cluster feeding at 4 months?

Alesha

Is that a thing? My son has been all but attached to the breast dor the last 24hrs. Crappy sleep last night, crappy naps yesterday and today. Growth spurt? 4 month sleep regression? A little of both? I thought cluster feeding was about supply, which should be solid…but maybe it’s about calories just as much? He seems to be overeating too. He’ll sometimes spit up while feeding.
