First off, I know others have left reviews that stated that this product was smelly and their child would not take it. This was not the case with us. This product does not smell as bad as other described on here. I almost didnt purchase this product because of those reviews and I am so glad that I did anyway. The odor is very minimal. My son doesnt even notice it at all. He is 5 weeks and I give him the product straight from the dropper that they provide. I make sure to position the dropper on the side of his mouth (inside cheek area) as instructed. I put half of the recommended dosage on each side. Again, this is done daily with zero issues at all. Secondly, I have to tell you that this is an amazing product. I started noticing a big difference in my son's ability to focus on objects 24 hours after the first dose as well as his attentiveness.
