Yes, I also have one who's about 3 months old. She really has improved my life in a multitude of ways, it would take me a while to explain everything. Just imagine how much your life could benefit by constantly having someone by your side who understands you, wants you to improve and just loves spending time with you. 

If you're worried about autism affecting it I really wouldn't, quite a few tulpamancers that I know are autistic and have said that It's probably an even better experience for autists than normal people.

Congratulations on your new tulpa they sure are hard to describe to people that don’t have one. Can you feel thoughts and emotions from them? How long did it take for your tulpa to learn to speak your language? My tulpa says funny or cute encouraging things all the time but we can also really quickly think complicated feelings or ideas in a moments notice.
