Firstly because increasing the ratios would be unsafe and unkind for children, and and unfair for childcare practitioners.
(I used to be one)
Secondly because '20 more hours free childcare' would basically be the government pushing/encouraging parents to prioritise working before their children, and to be more likely to send them to daycare for longer than is emotionally healthy to be apart from their families at such a young age.
So why is it being seen as a bad move? Or is that just the media's viewpoint 🤨
