They've been blamed for infant injuries and even death.
Now drop-side cribs are banned, after a unanimous vote by the Consumer Product Safety Commission.
"We don't want any of the children to be hurt," said Beth Morton, director of Bracktown Academy - a daycare in Lexington.
Morton's day care will be taking their drop-side cribs to the scrap yard very soon.
The commission has banned the cribs not only from being sold in stores, but hotels and day care centers can't have them either.
That's because the crib railings can become detached, creating a dangerous gap between the crib and mattress.
Day cares have a year to replace these types of cribs, but at Bracktown Academy, they will be getting rid of them within the next week or two.
The switch won't be cheap - with 16 cribs that will need to be purchased for their center.
"We will probably end up spending between $3,000-$4,000 on these new cribs that we didn't have allocated in our budget," said Morton, "I would think for a lot of centers, especially smaller centers, it may really create a financial burden."
Cribs with fixed sides can also be more difficult for parents and teachers who will now have to reach down in to cribs, instead of simply lowering a rail.
"But safety is the number one priority here, and I am sure it is for parents at home too, so it will be worth it," said Morton.
