Glass & Steel Bottle Starter Kit
Honey goes in wax, not plastic. Milk can go in glass or steel.

Step by step
- Start with 2–4 small borosilicate glass bottles (4–5 oz) with silicone sleeves.
- Use medical-grade silicone nipples; replace when worn.
- Never heat milk or sterilize in the microwave in plastic.
- Cool sterilized water before mixing in plastic parts (if any).
- Add a stainless option for travel later.
