No more naps?

My baby will be 18 months tomorrow and she has been refusing naps all week! She doesn’t show any signs of tiredness at all. She even fights going to sleep at bedtime and most night doesn’t go to sleep until after 10 even though our routine hasn’t changed one bit. Her daddy had adhd... he used to take a bunch of medicine when he was a kid. Is this a sign of it? Like she is a wild child for sure! She’s forever jumping off the couch and literally running around our house all day. She hardly ever just sits or watches tv. I know kids her age have a lot of energy but this is the complete opposite of my oldest at this age. Is she just done with nap time? Is that even normal at this age?
