My husband and I have started to notice the strong will of our 7 month old daughter. She can be quite demanding at times (no big surprise). Being first-time parents, it took us awhile to distinguish the difference between when she is crying for a reason (hunger, tiredness, etc) and when she's just angry or wanting her own way. My question is at what point should you start disciplining them to shape their behaviour and what methods are appropriate for a baby? Or is it still too early to be worrying about this?
