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....

Maybe once your baby fall asleep, move her to rocking chair? My son sleep in rocking chair during afternoon only sleep in bed at night or when i latch him. But most of the time he sleep on rocker, as he will sleep longer. If not you can try let her sleep in stroller, can train her when go outside can sleep in stroller too.
