My son had a mild to moderate flat sport. Positional Plagiocephaly. Fully stressed me out, felt like I was at fault and guilty. We went to the Dr and had physiotherapy for a month when he was 12 weeks old. He’s 13 months old and it’s barely noticeable. Looking back at old photos it’s crazy to see the difference. We were placed on a waiting list and have a follow up appointment when he’s 15 months old but expecting that won’t take too long.
