not letting baby nap.

So just recently I've come across moms who don't let their babies nap after a certain time in the evening so they can go to sleep early at night. I let my daughter nap around 4 or 6 but then she's wide awake at night. If I dont let her nap she's extremely fussy and I don't know how to deal with that. I want her not to nap in the evening that way it's easier for her to go to sleep at night. How do you moms do that?
