Are plastic baby bottles safe if they’re labeled BPA-free?

Generally, yes. The FDA and EFSA consider BPA-free polypropylene bottles safe. To further reduce microplastic exposure, avoid heating formula directly in the bottle.

How often should I replace plastic baby bottles?

Every 4–6 months, or sooner if you see scratches, cloudiness, or cracks. Damaged plastic can leach more particles.

Is it safe to sterilize plastic baby bottles in boiling water?

Yes, once — to sterilize a brand-new bottle. Repeated high-heat exposure can degrade plastic over time. After that, warm soapy water or a top-rack dishwasher cycle is enough.
