Last feeding... I'm I doing something wrong?

LL

So, I just started my LO who is 19 weeks today on solids. For her last cereal feeding which should be the last one before bed she is usually super fussy and just wants to nurse and to go to sleep. If I feed her any earlier it will be super close to her dinner and previous nursing time. Suggestions!?! For the recorded I am a first time mommy so please give advice! I'm I doing something wrong?
