The daycares our kids have gone to have all had instagram feeds that you can skim for similar information. It’s useful when we want to come up with photos to share with relatives, but there’s a huge ‘squeaky wheel’ effect, where one often finds that a couple of children with concerned [and/or neurotic?] parents will dominate the photo pool.
(As far as this as ‘surveillance’, I’m actually fine with it for 1-2yos - they’re fairly oblivious - but I think it gets creepy somewhere on the road to age 5.)
