I kind of don't like how some moms are answering this to say that it means your child is "average" - because it doesn't mean that. It more means she is "in the middle" - she is bigger than roughly 49% of children her age and is smaller than roughly 49% of children her age.
Also the reply that there is no need for concern unless the "height and weight are not proportioned" is also not accurate. Just like adults, you will have some who are "tall and skinny" and some who are "short and stout". Since my son's 2 week appoinment he has been in the 90th percentile for height (he is longer than roughly 90% of children his age) and 50th percentile for weight (about half of children his age weigh less than him and about half weigh more than him). These "disproportionate" percentiles do not mean there is something "wrong" with him - it simply means he is "tall for his weight" or "skinny for his height". Most likely my son will be a tall adult.
Doctors use your child's percentiles to compare their growth over time. Like another mother said, if your child was consistently in the 50th percentile for weight and dropped to the 20th percentile or rose to the 90th percentile they may want to take a look at your child's nutrition. Same goes for height percentile - if it changes drastically it may be a red flag that something is wrong.
A child who is always in the 10th percentile is simply a small child - it doesn't mean there is anything wrong. A child in the 90th percentile is no better than other children - only taller or heavier.
Sorry to go on, but I always like thorough explanations/answers and am never short on words! Hope this answers your question (even more than you care to know!) Ha ha!

It means your baby is right in the middle, growthwise. 50% are bigger than her, 50% are smaller.

that is perfect. If she was in a room full of girls her age, half of that room would be the same height and weight as her. I wouldn't worry about anything unless they say that she is below 10 percent or not on the chart.

I disagree a little with Amy regarding when there is a problem...2 of my kids have drastic differences in the percentages for height and weight (one of them is 84% for height and 28% for weight) and there is no worry because that is the way they have always been. Basically, you just want to watch her growth curve. She should stay close to on the same curve....whether that is 50% or 5%.

50th percentile just means is that fifty percent of children her age are larger than her and 49 percent are smaller. If her weight and length are in proportion with each other, and they are, then she is doing fine. My son was never even on the growth chart, he was so small. his weight and length was always in proportion so the doctor never worried. If she suddenly falls off the growth chart or her weight or length gets out of proportion then the doctor could become concerned. For right now, keep doing what you are doing.

There is no cause for concern with 50th percentile. The doctors will get concerned if your baby's weight is drastically higher than their weight or the other way around. If height and weight are close to each other, doctors will not be concerned. My son went off the charts when he was 6 months old and didn't go back on until he was 4. At 11, he is 75% for height and 65% for weight (since his H1N1 fight - he was 70% for weight before that). There could be reason for concern like Amy said if height is at 80 and weight is at 30 or 40 (or lower). It is not necessarily "skinny", it could mean that a child is not gaining like they should. this is not the case with every child but it is a red flag that goes up. Each child is a unique individual. Know your child.

That's good! It just means that your baby's height and weight is greater than 50% of other babies. My daughter was in the 50th percentile at that age too.

Actually Kathi, my daughter has been in the bottom 3% or lower since birth. her physicians are not worried since she is growing - i am a very petit woman from a long line of very petit women, so it stands to reason that my Lily will be a very petit little lady. there is nothing wrong with being in the lower 10%.

I have 3 kids and they always show me there percent as well. It is just to show you how they are growing. It is not a good or bad thing. It is just a way to measure your childs growth. The % chart/curve is just a tool to show you how they are progressing. It can alert to a problem or in my daughters case a good thing.

50 % is average, above is bigger than average, below is smaller than average.

They are only averages, but your ped. is saying your baby is average.

50% is the "average" so your daughter would be the average size of most babies her age. My daughter was on the 10% so smaller then normal and was always smaller then other babies her age and younger.

There really is no good or bad, unless the height and weight drastically differs. If she was 20% for weight and 90% height, there may be a problem. Actually, 50% is right at the average height and weight for an 11 week old. This means that your daughter is the same as most children. My girls were always in upper 90%. They were 9 lbs at birth and very tall. The % is just a way to track the average compared to other children the same age. Dont' worry, she sounds pefect!
