As a mom with 3 kids under 4 who have always shared a bedroom, I highly recommend bunk beds! They are solid wood and come apart into two twins just to switch things up. The room is JUST big enough for the twin beds, my baby's crib and a couple dressers. We also put a dresser in the closet and raised the hanging bar to make room. They are currently stacked in a bunk bed format just to have more room in their bedroom. I don't have much of a problem getting up there to change the sheets but my husband couldn't if he tried lol. We bought them used on kijiji for $150 including the mattresses. The only concern I had is when the daycare kids wanted to attempt to climb the ladder. So the kids bedroom is always off limits and is only used for sleeping in. No toys or anything allowed in the bedroom.
