(CBS) Federal officials are sounding the alarm about potential danger from more than 2.2 million cribs made by seven companies, including some of the biggest names in the business, and they're being voluntarily recalled, reports "Early Show" Consumer Correspondent Susan Koeppen.

To see specific model numers, hazards, remedies and more, click on the company names below:

-- Child Craft (this firm is out of business)
-- Child Craft, again
-- Delta Enterprise Corp., of New York, N.Y.
-- Evenflo, of Miamisburg, Ohio
-- Jardine Enterprises, of Taipei, Taiwan
-- LaJobi, of Cranbury, N.J.
-- Million Dollar Baby, of Montebello, Calif.
-- Simmons Juvenile Products Inc. (SJP), of New London, Wis.

The Consumer Product Safety Commission says the vast majority of the cribs involved have drop-sides -- sides that drop down and could fail, leading to babies becoming entrapped and even suffocate.

But cribs with fixed (stationary) sides are included, as well. One design could even result in kids falling through a crib to the floor.

There are reports of 27 kids being hurt by the cribs.

CPSC Chairman Inez Tenenbaum tells CBS News the recall "is part of our effort to clean up the marketplace of unsafe cribs."

The cribs were all sold between 2000 and 2009.

Consumers are encouraged to get free repair kits from the manufacturers to immobilize the drop-sides -- and NOT to try to fix the cribs themselves -- that frequently just makes the situation worse.

And, until the crib is fixed, have your child sleep in a pack-'n-play or a mattress on the floor, Koeppen suggests.

The CPSC has recalled more than 9 million cribs over the past five ...
