Hi,
I live in Horsell and have a 6 month old.
There is baby sensory in Knaphill (classes are opening for booking over half term for the next term so I'd get booked up early)
There is a lady called Emma who does a baby massage course at the Salvation Army church in Goldsworth Park (on the edge of Horsell and also where weigh-in is on a Wednesday from 9.15). She is fantastic and there is homemade cake!
The Lightbox does storytelling every other Tuesday morning at from 11, but you have to be there at 10.30 to get a ticket. It's aimed at all under 5s, so there is a break in the middle to do a little craft but the babies still love it and they don't mind littlies going. It is a suggested £2 donation and there is a good coffee shop there to waste the half hour before it starts.
The Nest is run by a group of mums through NCT (you don't have to be a member) and is in St John's Memorial Hall on St Johns Lye on a Thursday from 1.30 - 3, I think that is still a £2 suggested donation.
There are local surestart centres too, but depending where you are in the village will depend where you get assigned.
Also, a date for the diary - 28th November is the Horsell Christmas Market, the Christmas Tree festival at the Church and the Children's Fair at the Village school.
Hope that all helps,
Fi
