Hi L., It sounds like you got some good advice. That's actually a good question, I've noticed my head is kinda funny shaped as well. I couldn't help but add my two cents worth but it's not really advice, just something funny. I noticed that you have two boys and being the parent of several boys and girls who like to be wild indians most of the time, you might be able to use this as a "see you could get a big dent in your head like mine the next time you......" fill in the blank- jump on the bed, hit your brother with that toy, etc. just to freak them out for a second. I've been a mom for almost 20 years and every little thing that you can say to defuse a situation for even a second especially if it's strange, gives you a moment of peace. Plus it really makes your kids think-use their brains which seems to happen alot less when they turn into teenagers. AAHHH!!! Hope this makes you laugh!
