Ugh, poor DS2 is developing a flat head... OH NO.....

I have spoken with the GP, twice,once at 3mo, I made a special appt to discuss it, and was fobbed off and told to discuss it at 4 months, and then and all he did was give me a referral to a plastic surgeon, who laughed at me when I rang to get an appointment....

Basically, DS sleeps with his head to one side and tilted back, and no matter what I do, where I move him, he wont move... And his head is starting to take on a parallelogram shape... Poor kid...

So who do I need to see to help???????? And what can I do???? I dont want this to get any worse....

Thanks..........
