i heard from nurse at 1 year old vaccines too, i dont care, i think they will not use bottle when they are ready, yes, my baby uses straw and only can play and "bu" all the water out....sorry, it may take 1 hour to finish half bottle, no point. i think they will learn as they get older.
i think if even drinking with cups or bottle need training, as a mother we will be too tired, every thing of a kid need a training......we must take it easy. there are so much to come, toilet training, go to school training, eat with spoon and fork training, walking training....
