    • After reading up about the importance of the microbiome and on discussing it with my friend, who is a nutritionist and recommended this product, I felt it was important to give my toddler an additional probiotic supplement to support this, particularly as he was born via C- section. My toddler has also had intermittent issues with his bowels, most notably a lactose intolerance in the first year of life as he was unfortunately formula fed due to issues with breastfeeding. I was happy with this product, it was relatively easy to administer although my toddler is a massive wrigglebum so it took a few goes sometimes! It was reassuring to know that if the dropper touched his mouth (which inevitably it did!) I could store the product in the fridge without the contents being compromised. My toddlers digestive system appears to be in good order since taking this product, he has less wind and less loose, offensive poos. I would certainly recommend this product for anyone who is looking for a good quality probiotic for their baby or child.

    • Very satisfied! My 1yr old baby was extremely prematurely born, without any particular issues in the digestive system. I trusted a close friend of mine who is a nutritionist and recommended this as a high quality and researched product. Giving probiotics is the best I can do for supporting the digestion and absorption of nutrients, as well as the immune system of my preemie. Drops are easily given directly from the dropper and taste great! and this means that I do not necessarily have to mix them in milk, baby really loves them! Poopies smell and look normal, no adverse effects at all in almost one month use. I hope the product becomes available in Greece soon, so that I can avoid waiting for the delivery from UK which takes really long.

    • Ordering more! The results of our 1 year old taking this product for just one month are very noticeable! Farting - good improvement.. Very happy with these results. Great product, and the kiddo loves taking it as well, straight out of the dropper! It is now one of our daily rituals.
