Diaper changes

Until recently my LO was staying home with me, and I was checking her diaper every 2-3 hours unless she pooped or I noticed her diaper looked heavy. She recently started daycare and I’ve noticed there is a time every day where she’s going 3.5-4.5 hours before having her diaper checked. Is this too long or normal at daycare? I’m trying to decide if I should complain about it or not. She’s not soaking through the diaper or getting diaper rash.
