Aliza is obsessed with drinks bottles (in particular, 500ml soft drinks). If she sees me put one down, she immediately lunges for it. I think this is for 2 reasons: 1, she sees us drinking from them all the time and therefore concludes they must be interesting; 2, they're an interesting shape. She's really intrigued by them.
She's also very interested in getting the caps off, so we have to make sure there isn't anything left in any bottles we leave around!
