You'll probably get differences of opinion on this one.I for one do not ignore my children for any reason.If a one year old is whining there is a reason they are either not feeling well,tired,hungry,wanting some cuddles or they are bored so if you can tune into your child you can figure out what is wrong and help them. when their communication skills improve then you can teach them that they must tell you what is wrong in their ordinary voice or you can't understand what they are saying that usually breaks the whining habit over time but a 1 year old is a bit young to understand that yet.
