my boy sleeps on a yaolan during nap time only.
for me at night STRICTLY NO YAOLAN!~!!
Y? Becoz if in the middle of the night he cries then i got to rock him to sleep, later he cannot sleep without rocking so means every now and then got to rock meh?
it was hard time kicking off the yl habit at night at that time coz my mother in law took care of him for 3 weeks during confinement, all using rocking to put him to sleep.
till now my boy still sleeps in a yaolan during naptime. Sometimes he can sleep for flat 4hours.
to me using a yl is ok in the daytime, but not nighttime.
