We did not, of course because
our kids were both adopted.
Our eldest one, our son JO, had never before seen a bed in his entire life! In Korea everybody sleeps on the ground, on a carpet. He was terrified of his bed with bars! The only way I could make him fall asleep, was by lying on the mat together with him! It took us 3 weeks to make him accept his own bed
Our daughter didn't have any problems at all; at the orphinage she was used to sleep in beds with bars.
