So, I normally just delete the emails about crib standards because my father-in-law built mine; it isn't a drop-side either. However, I decided to read the one today from my health department. I'll just copy and paste the text from the email and highlight the important information:
You can find the "attached material" mentioned above here. It's the pdf about New Federal Crib Standards.
1. Determine if your current crib meets the new standards.
2. Decide if you want to buy a whole new crib if your current crib does not meet the new standards. You might decide that you would like to use a pack n play instead of a crib due to the cost of cribs.
