My question to you would be how does your doctor feel about your daughter? Does the doctor feel she is healthy? Does the doctor feel she is progressing well. My son (5 1/2) was always top of the charts until recently and he is quite healthy. The doctor mentioned as long as the numbers on the chart didn't go to one extreme or the other he wasn't overly concerned. Basically, I think he felt that as long as height kept going up, then the weight would even out for the most part. He also said as along as we were not feeding him too much of the wrong foods that he would be fine. The doctor recommended to keep our son active and moving. We have and my son is doing quite well. Not overweight and not underweight. Just perfect as the doctor always states at our yearly appointments. Variety of nutritional foods, proteins, and healthy carbs are what we have always strived for.
After speaking with my son's doctor I learned that the BMI index really isn't the best measure for children. It has been a while since I spoke to him so I can't really remember the reason. I trust my son's doctor though. We've used him since his birth. :-)
In a nut shell I'd talk to your pedictrician and get their opinion. :-)
Note: I'd also be careful with the healthy snack. Some of the snacks they claim are healthy, are actually not the best choices. I spoke to a nutritionist about my son last year and my eyes were open to a lot. For example, too much fruit can cause the sugar levels to rise. She recommended giving a protein with the fruit. Use healthy carbs... wheat products over non-wheat etc... Another thing I learned was that if you go to McDonalds the hamburger is actually a better choice over McNuggets. I found this interesting. It has something to do with the way they are prepared, I think. She stated to cut back on juices or to add water to juices. Things like that.... You may want to seek the advice of a nutritionist. I think our visit cost me $75, but in the end I learned so much from her.
