We're currently debating whether to send our 12 month old DC to nursery, or to hire a nanny. I can see some benefits of a nanny over nursery, however, I worry that DC will be less safe with a nanny. For example if the nanny takes DC to the park, what if the nanny doesn't watch DC closely and DC runs off, same with crossing the road etc. Or what if the nanny is distracted and DC picks up choking hazards. I think this worry is exacerbated by MIL telling me she can always tell which ones are parents and which are nannies at the park as the nannies are the ones playing on their phones / chatting rather than interacting with / watching the kids.
In some ways nursery feels like a more controlled and therefore safer environment.
YABU - the nanny is a professional and will take good care of the child.
YANBU - a nanny is an unknown quantity looking after DC in 'the wild' where anything can happen
