Am I failing at this?

Hi ladies - I recently became a FTM on 14th Feb - my boy is fab however every single day for the last month he has just screamed and screamed and screamed at every nap time - I can see he is tired but he won't go down, he will only nap in my arms after a total melt down, everyday I swing between "let's make this the day we conquer naps" and "let's just leave him he will go to sleep when he is tired...right?" Am I failing at this? How are you ladies getting on with naps? How many does your lo have? How long are they awake for? How do u keep a consistent bedtime?
