My picky eater is 13 months and weighs 16.5 lbs. At her twelve month check up she weighed 15.5 lbs. Is this ok

She was 7.5 lbs at birth and gained regularly until about 9 months. She was 14 lbs at 9 months and has only gained two lbs since. She was fed until 7 months old. Then given soy formula because I was not comfortable giving her milk based anything until she was at least a year. However at 10 months I gave in and began giving her regular formula, besides that I fed her three times a day,and gave her snacks . She always had plenty of diapers, though sometimes wetter stool. She Goes #2 two to four times a day and sometimes it is very wet. She is very active. The Dr says I need to feed her more. I have begun feeding her solely table food. Eggs, cheese, cereal, olive oil, milk, veggies (avacado, spinach, brocolli ,peas carrots, sweet potatoes, white potatoes),french fries, bannanas, gs strawberries, pasta and sauce,she won't touch meat,or beans or rice, or yogu. I give her goldfish and iron supplimented gerber puffs, her cereal has iron and DHA, her milk has DHA, and so do her eggs
