i remember 19 years ago when my wife and I were lookng at Daycares, one we visited told us that parents weren't allowed to come to the daycare without calling first with the exception of the designated drop off times and pickup times. That if we needed to pick her up early of drop her off late, we had to call first and if we wanted to stop by at anytime, we had to call first, that we weren't allowed to just show up. That didn't sit right with us. i was like, thats a big fat NO.
