I have been telling my sister for almost a year that I have a spare car-seat she can use. I wasn't sure the cosco HBB she had for her almost 3 year old was expired, but it sure looked old and his shoulders were higher than the top slots. She said he was uncomfortable and finally took me up on my offer (and the seat was expired by a year). Thankfully her pediatrician had gotten on her for putting her older son in a booster at 3 and told her the law was 4 (not sure VA has that law, but I'll take it). She just couldn't leave him in the seat for another year with the low harness slots. If the doc hadn't said anything she would have found a booster for him when he turned 3 this summer. So glad my extra SureRide was in my van when I went to visit yesterday. Now he has plenty of growing room and I even attached the top Tether (she had never used one - usually removing them from the seat because they were in the way).
