Hi, I have an appointment with GP/ have spoke with HV just wanted any advice / experience while I wait please . I have notice that my 12 week old son only looks to the right when placed on his back / sitting up. No matter what toy/stimuli is to his left he won’t turn his head. I know he can(when I hold him a certain way he has to).while he moves all 4 limbs with excitement , he will use his right arm to bat/grab at toys. But does not control his left one. I’m unsure if it’s vision or something like cerebral palsy. I didn’t notice a stronger side with my older son so am really worried and wondering if anyone has any experience ? Thank you x
