Life Insurance Guidance

When it comes to life insurance on your children, how much do you advise that you take out. I have two children still at home and would like to insure myself along with my children. My oldest is out on his own and doing well. My kids and I are all three healthy, I thought about taking out a small policy on each child and a bigger one on myself and naming my daughter that is still at home the beneficiary, she is going to graduate this year and move on to college, she will probably live at home while she is in school, so if something would happen to me, I want my children to be covered and not loose their home and everything that we have worked for. They are good kids, with good grades and participate in many community activities with me. I have a great relationship with all three of my kids and donÂ't want them to worry about this sort of stuff, in fact I donÂ't want to discuss it with them, I feel it is not appropriate. I am looking for guidance on how much to take out and what type, I have been reading through the forum and see there are at least two different types of insurance that I could possibly purchase. I want to make the right choice, would appreciate any advice you have to give. Thank you August.
