My 18 months son not able to walk independently & won't response to us when we call his name

My son is already 25 months and he also don’t response to us when we call his name. He can’t talk that much either. Brought him to see pd at KKH and they suggested EIPIC but will need 6-9 months to be on waiting list before he can be enrolled. Meanwhile just have to keep talking to your son, read a lot of books to him, avoid screen time if possible if not limit to max 1 hour per day. Get down to him at eye level and partake in activities he’s interested in

hi .. how is your son now? does he respond to name?
