Off the Charts or should I say not even on the Chart

Ainsley had her 1 year well check today and weighed in at 17.0 lbs and was 29 inches long. So she will still be backward facing for sometime in the car but she has now out grown her infant carrier so she gets to move to the big girl car seat just turned backwards. All in all she is perfect just no longer on the charts weighed was. This is totally new for me considering that Bracken weighed 23 lbs at his 1 year and Camden was 21 lbs. At this time Ainsley at 12 months weighs what the boys did at 5 months. She is just petite they say, but we still have to go back in a month for a weight check. Fun Fun!
