Better to be too tall in Marathon or light in Parkway?

[teach1abc]

My daughter is almost 6 yrs old, 42 in, and 37 lbs. She looks like she is getting too tall in her Britax Marathon in my car. I bought the 2013 Britax Parkway SGL and noticed it says the minimum weight is 40 lbs. What is safer - to be too tall in the Marathon or a little too light in the Parkway? She occasionally uses a Britax Monarch booster seat in my husband's car because she outgrew her Roundabout last year. She can easily buckle herself and sits properly in the Monarch. I am torn or which option is safer. What do you think?

How is she too tall for the Marathon? Shoulders over the top slots or top of the ears over the top of the shell?

teach1abc, I know you probably already know this, but just in case, I wanted to mention that the Britax Monarch in your husband's car may be expired or almost so. According to Britax's website, the Monarch was discontinued in January 2008, and with a 6 year life span, the Monarchs are expired or the last ones to be manufactured will expire next month.

Safer than too tall for the Marathon OR too light for the Parkway would be a booster that is rated for 30 lbs, such as the Graco Turbobooster or Affix. Assuming you're in the US, not Canada. If you're in Canada, you'll need a combination seat and need to keep her harnessed.
