Really like this probiotic for both my baby and toddler. Easy to give straight or mixed in something. The company is also great to work with, and answered my questions quickly. The only reason I give it 4 stars is because the bottle says a different dosage then they email you after you purchase. Bottle should be updated with proper recommendations. Also, just make sure not to put the dropper too far into the baby's mouth- I did that the first time and he quickly drank the entire dropper full before I had time to just drop a couple drops in his mouth.
