Dc (9 weeks) heavily prefers turning head to the left. He can move it to the right but not fully. He's a great night time sleeper so spends 9 hrs or so back sleep. As a result the left side of his head is flat.
Seen a physiotherapist and he told me to encourage movement to the other side which I've been trying to do since 2 weeks old.
What else can I do? Will he need a helmet to correct this? It looks really bad.
