DS is almost 16 months and all of a sudden REALLY whiny and needy with me (usually only with me). He is usually a very happy, independent boy. But in the past few days he wants to nurse just about every half hour. It's possible he has a tooth bothering him. He's been a realy slow teether and there's probably always a tooth working its way out. But he's never struggled like this with his teeth before. What's going on? Does it sound like an increase in separation anxiety?
