Transition out of crib: skip the toddler bed

Once our kids started to show an interest in climbing I switched to the pack and play which seems to be harder to climb out of, and by approx 18 months they were in mattresses on the floor - which seem safer than toddler beds to me, and are more comfortable on nights when one of us ended sleeping with a little one to ease the transition. They are now 2 and 4 and we still haven’t bothered with a toddler bed. We’ll probably keep their mattresses on the floor until they are ready for bunk beds
