I have had a parent of a child I used to care for ask If I have spaces for after xmas for her baby (will be about 9mths then) and also her brother's g/f has asked for their son who is 10mths. I am already registered to have 2 under 1 but I probably wont have space for both on some of the days (until 2pm). Should I ask Ofsted for a variation and what info would Ofsted want when I write to them?

It wont hurt to ask, say you need to know asap.

they will need names dob, children and ages of current children and you routine.

It will also help if you mention they are related (presuming they are)

They are related but only as cousins. Has any1 had a variation for children who are not brother/sister?

I would ask - they can only say no.

If you show in a grid who you have when it helps them see where the overlap is needed and the ages of the children affected.

I would state in your letter that these are children returning from previous care and that is usually counted as continuity of care.
