It's come to my attention that a lot of my parents' friends have taken the genius step of having a second kid. Great choice, parents! Second kids rule! But this isn't for them, it's for you, #2. The bad news is, your older sibling will always be older than you, no matter how many times you ask your parents when YOU will be older. Ain't gonna happen. The good news is, I am here to help you make your existence as second banana as smooth as possible. Just follow my steps below, and I promise, for as long as your parents are alive, you will ALWAYS be their baby. Unless they have a third. Which makes you the middle child. Sooooo many issues there. I am simply not equipped. But, I do know some people, so email me and I'll hook you up.
1. First and most important, immediately develop a fake cry. Work on this until it's perfect, and utilize it any and every time you can. For example, if you and your older brother get into a fight about whose turn it REALLY is on the Sit n Spin, if it isn't resolved in your favor in 30 seconds or less, bust out the fake cry. Some adult will come running, and I guarantee YOU will take ownership if said Sit n Spin. You see, you will ALWAYS have priority access to all toys, even your older sibling's. Why is this? Take note, my young friend. As the older sibling, your brother will be constantly reminded that he is old enough to know that sharing is "how we do things in this family". You, on the other hand, may be told now and then to share, but it's halfhearted, really. They just say that because they're supposed to. As the "baby", no one expects you to share. Win!
2. No matter how well you can really talk, never ever let them know you can pronounce your "R"s and "L"s just fine. Talking with a baby voice maintains the image that you are, in fact, a baby and just about guarantees that you can get away with anything. Don't worry about getting caught with candy or about hiding your mom's jewelry in the heating vent. When you get caught, just shrug, make a cute face, and say "But mommy, I wuv you." It also helps to shake your butt while saying "I'm shaking my booty!" and giggling. Grown ups LOVE this and it's a great diversion. Save the Shakespearean pronunciation for when you're with your preschool pack, and keep the grown ups in the dark.
3. Feel free to whack your older sister around anytime. If she tries to hit you back, bust out your by-now excellent fake cry and yell for mommy. Even if you started it, even if you BIT her, when your mom comes in to see what happened, just point to your sister and cry/mumble. Really lay in on. Runny boogers help. Why does this work? See #1 above. The same rule applies for hitting. Older siblings hate this maneuver, and they're on to it. Many parents are too, but because of rule #2, they're helpless. Win again!
4. Be prepared to hug and cuddle at all times. Parents are defenseless against it, and your older sibling has gotten very fickle about dolling out hugs and kisses. Their first little baby has grown up, and thinks kisses are for suckers. But YOU know better. You know the exact currency of kisses and hugs.
So there they are, my best tips, now available for you. Use them and you should be fine. I know because I use them all, every day.
