I need a neon sign!

This I think is the only way that Noah and Caleb will know where I am in the middle of the night without totally freaking out. Last night was insane! Luke woke up around 11:30 to eat (he went to bed at 7) and while I am feeding him I hear little footsteps downstairs then I hear the scream like someone was hurting my child. Seconds later (he must of scurried up the stairs in record speed) Noah comes bolting into Luke's room crying therefore waking up Luke out of his "dream feed." ARGHHHHHH! I finally got Noah settled down and started the task of putting Luke back to sleep. Fast forward 3 more hours and Luke is up again, Noah is sleeping next to me in my bed so I think all is safe. Minutes later while I am feeding Luke I hear the footsteps again downstairs and the scream of Caleb! Seconds later he comes storming into Luke's room and for all who know Caleb he is not quiet by any stretch of the means and can be quite dramatic. So now I have Noah(woken by Caleb's screams), Caleb and Luke up and I try to get the big kids to bed. I finally get Luke to bed. Wouldn't you know it that this seems to only happen when Carlos is out of town. I am just so thankful that I don't have to mess around with bottles (I honestly don't know how people do it) because I swear that would make my life even more difficult.
So a neon sign (good visual stimulation) pointing to Luke's room telling the boys Mama is feeding their brother might solve my problems!!!
