Set of 5 glass baby bottles (240ml and 100ml) and 9 nipples for breastfeeding consultation rooms. - Brand: Pigeon - Material: Glass - Size: 240ml, 100ml - Accessories: 3 and 6 nipples - Colors: Clear, Pink - Purpose: For breastfeeding consultation rooms Thank you for viewing. This set includes 100ml bottles, perfect for newborns, along with nipples and caps. Also included are bottles purchased on the recommendation of a teacher of the Oketani method, for use in breastfeeding consultation rooms, as the baby's sucking strength was weak after being discharged from the hospital due to premature birth. When washing the bottles, the Combi microwave sterilizer can sterilize three bottles at once, making cleaning efficient. The bottles themselves are light, so my arms didn't hurt, and I used these exclusively for the first few months because they were so convenient. The Oketani method bottles are also compatible with Pigeon's original nipples, so even if the baby's sucking strength improves, you can switch to regular nipples. They are compact but hold 200ml, making them convenient for a long time. I only used these two types for a while, and then I switched to exclusive breastfeeding, so the other larger bottles I had bought remained unused, haha. This is a recommended pair, so I'm listing it on the flea market. Due to the weight of the bottles and shipping costs, individual sales are not possible.
