Constant pooping!

My baby is breastfed and constantly poops. Sometimes during a changing we will go through 3-4 diapers because little squirts come out. I try to wait after I hear her make a poopy diaper to ensure she’s gotten it all out, but if she’s crying badly I’ll go ahead and change her and run the risk of the mid-change squirts. Anyone else deal with this? I swear we go through upwards of 20 diapers a day. Constant pooping!! Is it my diet? I just started a probiotic to see if it helps her at all. She is 1 month old.
