Hi, my son was like this too. Exactly at 15months. I went and see his paed. Even asked for supplement to boost his appetite. Paed said they have. But it doesn't work for every babies. I didnt take in e end. Eating half a bowl, or left over milk is ok. As long as she is eating. She may slim down a little. But make sure it's not too much. I gave my son fruits, raisins, bread with jam, cookies, even he dont eat proper meals. Slowly his appetite came back. Be patient..
