How do you tell someone.....

[nukedwifey]

My sister, for some reason unbeknownst to me, decided that her 6yo doesn't need to be in a booster seat.  When my mom told me that, I looked at her shocked and blurted out "that's illegal."  I find the best way to argue with people is to point out when they are doing something illegal as no one wants to break the law when it involves their child.  I wasn't positive at the time that is was illegal but was pretty sure.  My mom's response was "well, your sister said it isn't."   I wasn't sure how to argue with that!  I have a 2yo and I haven't needed to learn the specifics of that part of the law yet for my family.  I have since looked up the law and, yes, it is illegal.  So...... how do I go about telling her without sounding like a (5 letter word).  We're both pregnant and you know how those hormones can be but I don't want anything bad to happen.  I really don't know how all of this came about since she kept her older child, 8, in a Britax Regent until this all came about.  I figured she'd switch her 6yo into the Regent when she outgrew the convertible but instead took everything out.  How would you bring this up?  I don't know how to begin.  I was thinking maybe email and sending a link to the law pdf.  Of course the next problem is that the 8yo maybe should be in a booster but she's really big for her age, the size of a 10yo, and does pass the the 5 point test so I'm, at this point, picking my battles.  The 6yo is much smaller than her sister.

I'd research the law, tell her about the 5-point test, and ask her if she has spoken to her pediatrician.  My dd's pediatrician told me to keep my dd in hers until she is 4'9" or 80 pounds AND she passes the 5-point test so maybe bringing the pediatrician in will give you the back up you need. 

I think you should also ask her how her kids feel about the change.  My dd can see more and feels more secure in her booster even at 8 and knowing that a lot of kids stopped using a booster the day they turned six (and some sooner despite it being illegal).  Maybe pointing out how much more they can see to the kids when they use the booster in your car will help get them asking for the boosters back.
