Baby woke up dry?

Callie
My 11 week old son has been sleeping through the night for a few weeks now. Dad is on diaper duty when baby first gets up. Today my son's diaper was dry after 8.5 hours between feedings! I asked his dad if he's been actually checking to make sure the diapers are wet in the morning. He claims he has been. But knowing him he might just be saying that. I don't think it's okay for a baby to have gone that long without peeing, right?? He slept from 9 to 5:40. Should I be waking him up in the middle of the night to feed him because of this now? 🤷🏻‍♀️
