Sarong or rocking to sleep method, my mother use that since my elder sister till now my brother's kids, my son the same, its give u time to rest, sleep, do chores n etc...

once they r grown up, u can start to train them sleep on the bed.

IMHO we use it because we duwan to have depression or not enough of sleep, this will create more problems than bb addictions. Once bb sound asleep, we will transfer to the bed. my boy 25 months now

well its up to individual, my bil doesnt allowed this method at 1st, but surrender after a month, now his son r 17yo.
