Nap before bedtime

Ka

I read a post similar to this but can’t find it now. My baby (5 months) has been napping later in the evening. I get off work at 530. He nurses around 6-630 and takes a nap. My question is- if he naps until 7-7:30 how early is too early to try and put him down for bed? I’ve been just keeping him up a couple hours because that’s the usual awake time between naps. But then his bedtime seems so late. Advice is appreciated ☺️
