The "BPA-Free" Label Isn't the Whole Story
When parents started learning about BPA in the early 2000s, the plastics industry responded quickly: they swapped bisphenol A for other bisphenols — BPS, BPF, a rotating cast of chemical substitutes that, in many cases, have since been found to have similar hormonal effects.
"BPA-free" tells you one thing about what's not in a plate, while telling you very little about what is. If you're buying dishes that will hold your baby's food every single day for two or three years, it's worth understanding the real difference between plastics and food-grade silicone.
The BPA Problem (and Its Replacements)
Bisphenol A is an endocrine disruptor — it can interfere with hormone signaling in the body. Regulatory agencies in the US, EU, and Canada have restricted BPA in baby products, which is a good thing. The problem is substitution. When manufacturers replaced BPA with BPS or BPF, they largely assumed these were safer because they hadn't been studied as thoroughly. Subsequent research has raised similar concerns about both. Some studies on phthalates — plasticizers used to make plastic flexible — have too.
None of this means one plastic plate will cause harm. But babies eat from their plates every day, in contact with warm food — and heat accelerates the rate at which compounds migrate into food.
Microplastics
Research has found that plastic products, especially when heated or scratched, can shed microplastic particles. A 2020 study found that a polypropylene baby bottle, heated in the microwave, could release millions of microplastic particles per liter of liquid. The long-term effects of microplastic ingestion aren't fully understood yet — but the precautionary instinct is clear: if there's a cleaner option, use it.
Why Silicone Is Different
Food-grade silicone is made from silicon bonded with oxygen to form a stable polymer. It doesn't contain the carbon-based compounds associated with endocrine disruption. In the US, food-contact silicone must comply with FDA regulations requiring that materials don't transfer harmful substances into food under normal use. This isn't marketing language — it's a specific compliance category manufacturers must meet.
It Doesn't Leach When Heated
High-quality silicone is heat-stable up to around 428°F. It doesn't begin to break down at microwave or dishwasher temperatures, which means it's not releasing compounds into food when you reheat lunch. This is one of the most practically important differences for daily use.
It's Non-Porous
Silicone doesn't absorb food particles, odors, or bacteria the way porous materials do. It stays smooth even after hundreds of washes — meaning it's actually getting clean, not just rinsed.
Red Flags to Watch for When Shopping
- Vague material claims. "Silicone-like" or "silicone blend" are not the same as 100% food-grade silicone.
- Strong chemical smell. High-quality silicone is odorless. A strong smell can indicate fillers or lower-grade materials.
- Very low price point. Genuine food-grade silicone manufacturing has a cost floor. If a plate is suspiciously cheap, ask why.
- No brand transparency. Reputable brands are clear about their materials and certifications. If that information is hard to find, that's worth noting.
The Bottom Line
For everyday baby and toddler dishes, food-grade silicone is the cleaner, more durable, and more heat-stable choice. Ladydaidy plates are made from 100% BPA-free, food-grade silicone — microwave safe, dishwasher safe, and built to food-contact safety standards.
