Hi everyone! My 16 month old boy has been doing things im not sure if its an indicator of asd or spd. My son has a total of 15-20 words of those including sign language. He's social. He has good eye contact. He responds to his name 80% of the time. He points and claps (a lot, appropriately), high fives (loves doing it) waves, plays peek a boo, does so big, points to himself when I say wheres Jackson? I've noticed he likes to hold 2 balls and throw them then claps and makes a weird humming noise while he claps. He likes doing this a lot throughout the day. not all day but a good chunk. He likes laying on the floor (carpet specifically) and sometimes holds toys up in the air. Any advice? (waiting on appointment with pediatrician where I'll bring this up.)
