Silicone is widely used in baby products because it's flexible, heat-resistant, and generally considered safe. However, it may not be the best eating surface for the following reasons:

Microplastic Shedding (with low-quality silicone):
Some silicone can degrade over time, especially with repeated heating, potentially leaching siloxanes (a type of silicone compound) into food.

Act as endocrine disruptors, mimicking or blocking natural hormones.
Impact brain development, immune function, and metabolism
Linked to early puberty, behavioral changes, and even long-term fertility issues
It is not not fully understood in terms of long-term health impact.

Odor and Stain Retention:
Silicone is porous compared to materials like stainless steel.

It can absorb odors from cleaning products like dishwasher tablets, oils, and food stains, which may be hard to clean and can harbor bacteria if not sanitized properly.

Easily Damaged by Sharp Utensils:
Baby forks or teeth can scratch or tear silicone surfaces, creating crevices where food and bacteria can collect.

Environmental Concerns:
While more eco-friendly than plastic, silicone is not biodegradable and can be hard to recycle, unlike stainless steel, which is 100% recyclable and has a much longer usable life.

Can Feel “Grippy” or Sticky:
The texture of silicone can be tacky, which some kids (and parents) find unappealing as a direct eating surface, especially for neurodivergent children.

That’s why many parents prefer stainless steel, which is non-reactive, durable, hygienic, and doesn’t leach or retain food residues.
