How long does cluster feeding usually last? My son is going through his 3 week growth spurt and has been on the boob CONSTANTLY for the past 4 days... when does it end😭 also for any ladies who are wondering if their baby is cluster feeding or not, trust me you’ll know!! I always thought “is this cluster feeding?” But nope, you’ll definitely know when it’s cluster feeding... I seriously haven’t been able to leave my couch except to use the bathroom or grab something to eat because if my baby isn’t on the boob, he’s crying like he’s starving.. and I know he’s getting plenty to eat because I’m an over supplier!
