My LO (13 months) would hardly more than 1 or 2 oz from a straw or other sippy cup, and we are trying to wean her from the bottle. I tried the one above and she took to it right away! Drank 6 oz at wake up and also drank 6 oz shortly before her nap. Just thought I would pass this on if anyone else is having a hard time weaning from the bottle.
