Hegen Fast Flow Teat for 6m+

If you have a spare teat, you can try (but unlikely due to teat size). Babies at this age are usually more curious of their surroundings and also since they are exposed to more solid foods their interest and intake in milk tends to drop. You can try offering milk in straw/sippy/normal cups instead of bottles. This can help your LO to gradually wean off milk bottles as well.
