Claire has not been the biggest fan of a sippee cup. She refuses to hold her bottle and hates the idea of holding her own cup. Luckily our pediatrician said she was okay if Claire kept using her bottles until 15 months. In the past week or so Claire has gotten the hang of drinking water out of her sippee cup though. I am so proud when she learns new skill! She still has no desire to hold her bottle and don't even try putting milk in her sippee cup. She will throw it and throw herself on the ground in disgust.
