I guess I look at 2 year olds as being a lot older than most people do.
Blackcat any tips on getting a 16 mo old to use an open cup. This is a child who has some sensory issues. He freaks out and gags himself if I try to serve him something on a spoon and he is acting this same way with the open cup. I was just able to transition him to the sippy in the last month. If I put it on the table with him, he chucks it at me(and his mom). Mom wants to put him at the center across the street with his sister, but he can't bring the sippy with him.
