my 3mth old girl keep sleeping on her right side since birth and now right side of head is a bit 'flat' and some advice me to let her sleep on yaolan... will she be relied on yaolan? should I let her sleep on yaolan? troubled....

everyone says my boy's head is very nice after he sleeps in yaolan. when at birth he also always sleeps one sided thus one side also flatter then the other side and that is when i intro yaolan, and baby able to sleep tru the night thanks to that too. as long u dont overuse the goodness of yaolan, i dont think there is any issue, cos im also a yaolan user since young. but then again, it depends on yr own thoughts to decide the pros and cons of it.
