Our youngest is 6. He has a huge firetruck that is so loud I swear Rescue 911 dispatches from some point in my hallway, an army truck that not only lights up and roars across the room but screams at me about "taking a hill" or some such nonsense. Oh and his new huge remote control dragon. Dang those fire red eyes and the dragon roar....scares the beejesus out of me while I'm innocently sipping my morning coffee (much to his evil 6 year old delight!) He loves those loud sorts of toys.
I must say I quite enjoy the days when the batteries run low and mommy "forgot" to go buy more.
P.S. You know before you have kids you just never imagine yourself hollering..."Michael Joseph, you come get your dragon out of the bathroom right this minute! It's NOT funny to scare mommy while she's peeing!!!!!" Somehow they don't cover this stuff in What to Expect While You're Expecting.
