Sorry Im not much help, my daughter had a bottle until 5!! She gave it up before school, along wiht her daytime nap!She had a bottle in morning and night. Was peaceful for me. However with number 2, I am going to give her a cup morning and night I think as soon as she's on normal milk. That's the plan, not sure how easy it will be!
It's also just not as relaxing having the cup. i think i enjoyed the bottle as much as DD1!! xo
