I haven't engaged nanny #1528 specifically, but from what I've generally heard, PEM nannies tend to be quite proactive, things like doing a checklist of essentials on day one, cooking extra food so you're not scrambling for dinner, and even flagging early signs like skin rashes on the baby without you having to ask. One thing worth knowing is that PEM has a tiered system, Gold nanny status costs more, but apparently you can sometimes confirm a Gold nanny while only paying the nanny-specification fee, so it's worth asking them about that upfront. The trade-off some mums mention is that the experience really does depend on the individual nanny, some are exceptional at reading your needs (like adjusting soup recipes to prevent engorgement based on your milk supply), while others are more straightforward and task-focused. So I'd say go in with a clear sense of what you need from her, and don't be shy to communicate early.
