Is it better to go with sleepy cues or stick to a routine? LO is 7 months

I’m confused. Yesterday my son was up at 6:30, got cranky for first nap at 8:50 and put himself to sleep in his cot for an hour and a half.This morning he was up around 6:20, and got cranky for his first nap around 7:30. I opted to keep him up a bit and then just put him down at 8, again with no fighting.These windows are both pretty different but he responded to both well. My question is do we just go with his cues or should we stick to a regimen and risk him being overtired?Bed time usually 7:30 by the way where he sleeps through until morning, and he has 2 longer naps a day. via /r/Parenting https://ift.tt/3iUDV5u
