There are lots of different schools of thought on this. A planner we met with shared a personal anecdote about how his own daughter was diagnosed with lupus at a young age and how a life insurance policy that he and his wife purchased for her before her diagnosis is the only one for which she qualifies. She is unable to obtain more because of this previously existing condition. He said that they were glad that they purchased this for her. Based on this story, we purchased a small policy for our child. He has the option to take it over and add to or cancel, as he sees fit, when he is older.
