It's up to Nic to confirm but it seems pretty conclusive- the 2 year old was born at 6 Leader Street(transcribed as 60)
Mum born Islington and called Beatrice in previous censuses.
Using a combination of the various free indexes available and some cross-referencing we come up with this household in 1911:
James Brown born 1867 New North Rd Islington
Beatrice Brown born 1883, Manuhan Heads New Zealand
Charles Brown born 1909 60 Leader Street Chelsea
Jennie Brown 1910 49 Tidey Street Bow
A good mornings work I think
