Bests & Worsts Reviews from Amazon

So i never write reviews but i had to for this product. I decided to buy this product because of the amazing reviews everyone posted about their children showing signs of improvement in some type of development delay. I have a 23 month old son and he doesn't talk, an obvious speech delay and possible autism. I'd say after giving this product to him for about 2 weeks i noticed he was being alot more vocal. He began making new sounds. His attention span improved tremendously. He didn't seem so spaced out like he used to be. An overall change! We are now on his second bottle and today he finally said new words besides "mama" and "papa". He said "up" and "bravo"! This was such a precious moment. If you have a child with a speech delay or any type of delay, you know that any sign of improvement is literally the best feeling ever. I'm so grateful for this product. I saw a few comments about how this product can get messy and honestly that small defect does not compare to the improvement it has given my son. I recommend this 100%!
