Should I phone social services or not?

My neighbour has been screaming and swearing at her 3 year old for sometime now, from 6 in the morning until she leaves the house for nursery run and when they’re back in the house from 5pm she’s screaming constant at her child. I get that everyone can be stressed and I’m in 2 minds about calling social services but I’m now worried for both of them. I have video and voice recordings for proof. Do I or don’t I?
