Not eating enough :/

So I notice my daughter who is 13 months old doesn’t really want to eat much. I mean she only takes a few nibbles of something and then she is done. I constantly offer her snacks & meals but it seems like she doesn’t want anything. There are a few foods that she will eat a lot of like eggs, yogurt, rice and fruit but I don’t want to make her picky and just offer those foods to her all the time. Any advice!?😖
