HOW MUCH, HOW MUCH HOW MUCH...

Now that I am older, am a mom, etc. I am learning all the new "rates" that are appropriate in this day in age. In other words, I am learning how much money kids make, today! So, I need to know the going rates of things like the tooth fairy, what to give kids for their Bar/Bat Mitzvah's, their communions, shit like that. How much allowance is the norm, what's too little what's too much?1?!? How much to give kids at their sweet sixteen or graduation, it's all new to me. Who do I ask? Will they know what's appropriate? Will I seem cheap? UGH it NEVER ends! XOXO BTC
