What's the right time to start baby foods? A key study gets a second look.

If you're a parent wondering when to start your baby on solid foods, you know how confusing the advice can be. A key U.S. study that helped shape some of that guidance has just been retracted and republished. This is an official notice that the researchers and journal editors have taken a second, careful look at the original work. It's a standard scientific process for ensuring accuracy, but it means we should view the study's specific conclusions with a bit more caution until the full, corrected report is understood. The notice doesn't tell us what the study found or if anything was wrong—it just tells us the process is happening. For now, the best takeaway is that science is self-correcting, which is ultimately a good thing for getting reliable answers to important questions like this one.
