babycoco: initially she chewed, too coz she was teething. then she took a sip, choked and totally refused it after that. every day, we just kept letting her play with it until one day, out of the blue, she kept wanting to drink with it. i think babies chew to assess, explore the straw - trying to figure it out, whether it's good enough, any harm, etc. keep on trying
or maybe A wants to drink from a cup instead?
