We have an after school/pre-school nanny for DS5 and DD2. She started two weeks ago, but is our third after school nanny/babysitter (others left due to uni ending/starting, all very amicable). She's hired via a local agency that matches mostly students with after school childcare jobs. She previously looked after some slightly older primary school DC, and her reference was solid. So far, she's needed a bit more hand holding than other nannies but otherwise seems fine. DC have made no complaints.
This morning at school drop off, another mum - who is an acquaintance, not close - pulled me aside to say that she'd heard the nanny speaking harshly to my DS at pick up earlier this week. Yelling his name, telling him that she'd told him three times to hurry up. She said that it seemed over the top for a small child. I thanked her for the information, but now I don't know what to do with it?
DS can struggle with listening - partly because of some additional needs, but sometimes also because he's playing up, so I can fully believe she had told him before and he was dawdling. Sometimes he does need to be told firmly. And the nanny has only been doing pick ups a couple of weeks and maybe it was a stressful day. And I don't know the other mum that well and what seems harsh to her might not be to me.
That said, I don't really want the nanny loudly berating my kids in the playground for all to see. I'd rather she took DS to one side and reminded him that he needs to listen. But I'm not sure if/how to raise this with her, without her feeling like she's being spied on? Would appreciate any advice people have.
