How soon is too soon to introduce young children to new people your dating?

ok so the reason I ask this is my ex introduced our 5 yo that had ASD to his new "freind" and her daughter, in my opinion way to soon. Not just at the park.. at her house. They have been seeing each other for just under a month. We had a previous discussion regarding this subject prior to my ex meeting her. When we met someone we would wait for it to be at a more solidified stage before introducing our son to potential long term partner to avoid our son getting attached to someone that won't be around long.
How long would you wait to introduce your child to a new potential partner?
