Almost two month old keeps pooping

My lo will be two months old next week and I've noticed since this morning, she's been pooping non-stop. Her poops no longer have the seedy consistency,  it's more runny and light brown. But she's already went three times today, I don't know if she's getting sick or anything. She doesn't have a fever or anything. Is this normal? She's exclusively breastfed with the exception of needing a bottle of bm while I'm working.
