is weight beginning to be a problem? Adoption issue

My daughter is starting to show a little bit of a pudgy tummy and hips.  I have also noticed she is starting to develop. She is adopted so I don't know what her birth parents body types are (ex. We don't know if her birthmother has a larger body type, overweight, etc).  She is a very active girl but loves to snack which we control.  Is this something we should be concerned about?  Is she too young to go by calorie intake?  I don't want to set her up for long term weight issues.  I just want to do the right thing.

Thanks!

Her weight is between the 75-90th percentile and her height is just above the 50th percentile which indicates she is normal for her age. For her age she needs 2000 calories per day to grow because she is still a child.
You seem to know that it is recommend increasing children's physical activities (play, dance, sports) to lose weight, and not lower calorie intake due to the need of calories for growth. Suggest dancing which is fun and will help to maintain/lose weight. Limit time in front of the TV or non-active-video games. There have been studies showing the longer the length of time a child sit in front of the TV, the greater the weight gain. Suggest limiting high sugar drinks/snacks and try replacing with low fat milk/yogurt or fruit/popcorn/cheese. Additional suggestions: cook only low fat meats (chicken, fish, loin of pork) or non-meat sources (soy products, nuts), low fat vegetarian combinations (rice & beans, pasta & beans, low fat cheese & pasta), fat free or low fat dairy products (skim milk, 1% milk, low fat cheese, low fat yogurts, low fat soy milk/yogurt), use plant oils, non trans-fat margarines, and eat a lot of fruits and vegetables. Eat daily high fiber breads and cereals (oatmeal) and limit ‘junk’ foods. Hoped that helped you.
