20 month son is a late talker. Babbles a lot but only has a couple of words. Understanding is good however and he can communicate easily with us with pointing and nodding etc. eye contact good but not always with strangers. Very energetic. Sometimes makes an odd throaty noise that he’s squeezing all the air out his lungs to make the noise (hard to explain). Anyway he mouths things a lot. Has his hands in his mouth a lot of the time too. The thing that’s concerning me the most is he’s started looking out the side of his eye while walking down the hallway and also did it running outside in a circle. Looks a bit odd and I don’t really know any other toddlers that do it. I’m starting to worry now that he has a few things that point to asd. Anyone have any suggestions/advice/thoughts? Thanks in advance
