I bought this kit and would love a pack of just nipples!** A: Hi, unfortunately we don’t have just the sippy nipples but we will soon bring that to the market. **Q: Do you need to use weight straw? Can the sippy spout be used without the weighted straw?** A: Yes, the weighted straw is removable and you can use the sippy spout nipple by itself. **Q: Can we purchase just the straw nipple by themselves without the rest of the kit? I have a bunch of handles and cleaning brushes from previous purchas** A: Hello, unfortunately we do not sell the straw nipple separately for now. We are working to put that on the market in the future. I can send you a replacement part. Please contact me with your order number.
