Why would two-year-olds not thrive in schools? For starters, they are likely to be in nappies, have limited language and may well be drinking from a bottle. Next, they need higher ratios of staff to children as they need access to stable attachments with a key person and sensitive and responsive care from everyone.
The term 'school ready' gets bandied around a lot in early years care settings. Education Secretary Michael Gove has complained that many children arrive in school "totally unprepared to learn" and just like week Sir Michael Wilshaw, Chief Inspector at Ofsted argued that "a significant minority of children are simply not ready for school".
