It's a big house but surely not for that many kids plus staff plus cots plus toys. Kids need space.

Also not sure how "wonderful" the Horniman escorted by the poorly paid overworked young nursery staff I'm sure they'll employ. You can identify troupes of nursery staff at the Horniman a mile off because they'll be chatting only to each other - never to the sad, passive looking (often tiny) little kids in the buggies they're pushing. They always look to me like they've given up a bit. Maybe they get more attention back at the nursery but I doubt it. I wonder what line on "quality care" the parents were sold when they signed up.
