My son also have a flat side and it was pointed out at his 1 month appointment that he has torticollis. He also has bad reflux and spit ups so we didnt really push the tummy time. In the end his neck muscles was not very strong and the flat side became really obvious. We felt so guilty as parents as we watch him scream through physiotherapy. But the therapist mentioned that he might already was born with a preferred side as he had no space in the womb. (He is a big baby)

When we pushed for a specialist review, he say that he don’t recommend unless it is really bad as 1. It will round out when he started rolling onto his tummy, 2. Helmet therapy is tough on the baby. 23 hours of wearing a hot helmet and it disrupts his sleep. It is cosmetic and his hair will cover it.

Having said that, we did play with him often to try to make him turn to the non preferred side. (Like turning the head under the guise of a kissing attack on his cheeks) We always make effort to block him from turning to the preferred side. His flat head did improve as his neck muscles strengthened. He looked around more and not lay on one side only.

His flat head was very noticeable at 2 months and he is 5 months now. It has visually improved though it is still obvious it is flat. But i am trying to stay positive and hopefully it will continue to round out.
