Breakfast battle

My daughter is 21 months and it’s just not into breakfast. I took her to her for her check up and the doctor doesn’t seem concerned just said that as long as she’s getting one big solid meal day it’s for her is dinner

for the problem I’m having is, she’s hardly eat her breakfast so we’re snacking all morning and even if I try to choose something healthy and she’ll refuse it then I find that she’s eating lunch at like 11 15, 1130 cause she is straving which I mean fine if it works for her works but i think this lunchtime to be way too early.

any tips or tricks of something I can give her outside of breakfast that will make me feel her a little more full before lunch!
