My son was given this for his birthday a few years ago, he is Autistic and will only drink out of this bottle!! I was very excited when I spotted them on Amazon so have brought a few to keep hidden!! Like others have said, the image does rub off but, hey he loves it!!
I bought it for my 1 year old son and held onto it till he was 18 months as he was just pouring it everywhere. At nearly two he still is pouring it everywhere as he knows to turn it upside down and squeeze! i have put it away now till he is older.
