Hi all, what's the diff/pros & cons between yaolan and baby cot? Heard yaolan can prevent flathead!

just use a normal baby cot, train the baby to sleep on cot since young is better. my baby till now (8mths old) able to sleep by herself. and she doesnt hv flat head, cos i dont gv pillow. i just put a clothe on her bed to prevent she spit on bedsheet. i also did a research, baby below 2yrs old better not to use pillow to prevent flathead :)
