She is 4 months old now and was only 5lb 14oz born, was sitting breech from 28 weeks and was also born breech. Her head at birth was flatter on the top and was quite long looking at it from the side. Her face etc looked normal and all her features were perfect. I have used the pillows to prevent plagiocephaly since she was born, and try not to leave her on her head for too long, BUT this is hard sometimes as shes a good sleeper. She did have torticollis on the right side of her neck from the birth (tight neck muscles) but she was never restricted in her movements and would always turn her head both ways. I alternated the side she slept on regularly but she would put her head wherever she felt comfy.
