Probiotics

Hi Guys! 

Im new today! I have a 3 year old little girl who shows every symptom of autism. She has not yet been diagnosed and I've had to fight to get her to be assessed, due to her having very good eye contact, sharing joy etc. I am constantly told that this means that she does not have autism By half the professiomals she sees! 

Anyway, sorry for that rant. i was wondering if anyone had found probiotics helped? I've read lots of research linking good gut bacteria (lack of) to autism. I wondered if anyone had used probiotics, which brands would be best for a 3 year Old. 

Thank you Relaxed️
