My son did the same thing for the longest time. We always just let him sleep, and he never once woke up in the middle of the night. Every now and then we would have to wake him up for his last feeding, and then he was out for the rest of the night again. He still to this day (at 1 year old) doesn't like napping at daycare, so he's always extra sleepy when he gets home. It has never messed up his schedule, but he only goes to daycare 2 days a week. It may be different if he went more, I suppose.
