YOUR results with YOUR baby on probiotics..

Just wondering if anyone out there has a baby with irregular bowel movements, and if probiotics worked for you with that issue? If so...how long did it take for you to see results?! Just started with mommy's bliss this morning, and added it to fresh pumped breast milk. Hoping she goes a little more regular! She went 6 days without going, and I had to do rectal stimulation to get her to go.
