Autistic toddler

Hey everyone, I’m just posting for some encouragement and positivity you guys always help. I’ve been feeling down because I’ve noticed my baby ( soon to be 2 in may) is veryyy different from others his age. He was a preemie born @ 3lbs 12 oz so he already is slightly delayed… but since he started daycare and has been seeing a therapist for his speech delay recently, both the therapist and daycare teacher says he’s showing most of the signs of autism . Yes he is still young for the diagnosis but I’ve been looking up and reading so much information about autism and he shows almost every single sign… I have worked with autistic children before since I use to work at an elementary school. They are so smart yet so different and that is what worry’s me. I don’t want my baby singled out or treated differently because of this.. I don’t want other kids being mean to him. The daycare teacher has also mentioned she may need to start calling me to get him sometimes because his tantrums are bad. I just feel like im not ready and Ik I have to gain so much patience . Im also a young mother.. I’ve been crying almost everyday about it since they told me they have concerns.. I’m scared of how life is going to be.
