After reading here I'm now concerned about my neighbor. Her son is the same age as my son and he will be 3 in a few weeks. She saw my husband installing my daughters new marathon the other day & was saying that she is going to put her son in a booster because he is running out of room in his carseat..now, I know he has to be at least 40 lbs. and 4 yrs. old to be in a booster..right? He can't weigh too much more than my son..my son is 34 lbs. I just don't know if I should say anything?? Plus...he's not even 3 yrs. old yet.
