I think the issue of childcare at conferences is really important. A free creche is just an issue of space, finance-wise. It's the work of a few minutes to work up a rota for volunteers.
This is the relevant legislation www.ofsted.gov.uk/resources/factsheet-childcare-registration-not-required
'If (excluding childminders) you care for children under eight for four hours or less each day and the care is for the convenience of parents who plan to stay on the premises where you are providing care or within the immediate area. This type of provision has no long-term commitment to provide care for children – for example, a shoppers’ crèche, a crèche attached to a sports centre or adult learning centre, or an exhibition – and covers services where children do not necessarily attend every day. '
Given that 70% of women will have children, feminist events ought to provide childcare where possible. Mothers can bring toys etc along which their children can share.
The Scottish Women's Liberation Conferences in Glasgow have had creches.
Go Feminist did.
Fem 11 did but it was shockingly bad.
Feminism in London does, I think.
I'd advocate anyone thinking of planning a feminist event to try to have a creche if at all possible.
The easy access guide leftunity.org/guides-to-access-and-inclusion/ here's really good.
