I have a little peanut, too, who will be 9 months next week and is only 17 lbs. She has been on higher calorie formula most of her life. She was hospitalized for 5 days when she was a month old because she had not regained her birth weight. After tons of needles, chest xray, cat scan, and being poked and prodded endlessly, they decided she wasn't eating enough. I was bf'ing at the time, so since she wasn't complaining, we didn't know she wasn't eating enough. She spent a month on 24-cal/ounce ebm/formula mixture, then gradually reduced it over the next month. Ever since, she's had formula that is measured as slightly heaping rather than level scoops, and we practically force feed her a few extra bites at meals (although she pretty much resists any additional now). Even with all this, she barely follows a consistent weight curve. She is extremely active (crawled at 6 months, and already taking a few independent steps), and her ped warned us that we may have a hard time keeping her weight gain constant, but since she is very advanced, and is growing consistently in height (95th percentile) and head circumference, he's not worried, even though she's below 3rd percentile weight for length. It took alot of months for him to reach this point, though. Once she started solids (at 6 months), she finally gained some interest in eating (particularly now that she can feed herself a few things), but still not much interest in the bottle. We work to get 24 ounces into her every day. She gets 2-3 tbsp of rice or oatmeal cereal (made with formula) twice a day, 2 fruits & 2 veggies (stage 2 jar or equivalent amount, and a couple tablespoons full of either O's or crispy rice cereal (organic due to corn sensitivity). We tried cutting back on solids, but she didn't take any more formula then. We try to make sure she gets avocado regularly, since it's higher in calories, but mostly we just try to make sure she gets nutrient-dense food.
Be careful going to high-calorie formula. They introduced dd to it slowly (22 cal first, then 24 cal) while she was hospitalized, checking her stools for signs that it was upsetting her tummy. Don't do it without specific direction from the pediatrician.
