So my son is nearly 9 months he does not focus on me other people or objects he will follow an object if he hears sound. When I am right in front of him talking or singing he keeps looking side to side and not directly at me it's as if hes looking for me. He is not rolling over or sitting up and his muscles are very relaxed. Physio said he will be referred to pediatrician and occupational therapy to see if he can get a high chair which he can sit in. I am worried as I have 2 other kids and know that things are different. Has anyone experienced anything similar ? Thank you
