Food help!! 1 year old

Hey mamas! My daughter is so picky with foods. She has been on whole milk since she turned one and eating regular food but she does not eat much food. We try and try and she will take a few bites and then be done with it. She loves whole milk though and we try our best to give her no more than 20 ounces a day (per her pediatrician) but sometimes we give her more because I am terrified she isn’t eating enough and she also screams for milk and won’t take water or any substitution. Any advice or anyone else going through this? It’s so frustrating and I’m worried she isn’t getting enough calories with food and drinking too much milk😫

To clarify she drinks water lol, I’m saying when she wants milk she won’t drink water. She has water with every meal.
