Hi everyone I'm after a bit of advice please!

I currently look after the children of 2 sisters, the youngest child is almost 9 months old. I have been approached by the brother of the 2 sisters to see if I can also have his daughter (they have just moved back to the area). I have space available, my only problem is the child is 6 months old! So I'm thinking that I can't do it! I used to be able to have 2 under 1 on my old certificate, but I know that that variation has been removed! The annoying thing it is only from Oct when the Mum returns to work till dec when the 1st child turns 1!

Am I right in thinking I can't do it Thank you
