Don't mention the camera because he'll just deny your access and then continue neglecting your child without you watching. Gather evidence and build a case. What he is doing is unacceptable.
What?! That’s absolutely awful. That’s neglect. I’d absolutely be saying something.
2.5hrs & your baby hasn’t been tended to? there is no staying in your lane?! dirty nappy & no food? he needs to see a doctor- might be an underlying issue here…
Girl I would speak up! Your baby deserves a diaper change at the bare minimum! I’m so sorry :( I would definitely say something to him
Dude 30 minutes or so is one thing but that is insane. Your child IS your lane.
