Ask your pediatrician at the 1-month check-up. Or call them and ask about it . It has more implications than just affecting "宝宝的头形". It could be because of the unbalanced neck muscles. Physical therapy is very useful. The earlier the treatment, the better. My child got the first physical therapy at 6 weeks. She only needed a few sessions. The therapist told us that we were lucky. Had she come at 6 months , it may have required months of treatment with less than ideal results.
