Cluster feeding???

Vicky
Good lord someone help me! The last two nights DD has been on the boob every hour. We've tried everything else but If she doesn't get the boob she screams! Tonight it started at 9:30 and here we are at 4:30am and once again she is feeding. Is it possible to overfeed her?? Husband thinks she's eating too much and then becomes super gassy and that's why she's awake and crying. The boob is the only thing that soothes her though.... I think my sanity is slowly leaving me!
