I always start my kids on a sippy cup around 6 months or so. So, naturally, it's Nathan's turn. He did better with it than I thought he would- better than his siblings did their first times. He liked sucking on the spout part.. like a pappy. It was water -cold water- and it surprised him. He was intrigued and kept going for more. By the end he was soaked but at least he was interested.
