You're right, you can't take on any more 1-year-olds until one of your current 1-year-olds turns 2.
The Jan. 2016 compliance date is only for children who were in care BEFORE Dec. 4, 2014, the day the Bill received Royal Assent, meaning it passed it's third and final vote to become law. Any children taken on AFTER that date have to follow the new ratios. They gave us a year to get things in order, so there wasn't a flood of providers all terminating clients at the same time. People go back and forth on whether or not we can take on more 1-year-olds right now because it is before Proclamation, but in your situation, that won't matter, since you are looking to take them on in the Fall, and that is when Proclamation of the Bill (officially making it law) is due to take place.
If your current two 1-year-olds aren't turning 2 until Nov. 2015 and Jan. 2016, you can take on one additional 1-year-old in Nov. and another in Jan, but you won't be able to have 3 under 2 at one time, since they were not ALL in care before this previous December.
The only way providers can have more than 2 under 2 right now is if they were all in care with that provider before this previous December. Then the provider has until Jan. 2016 to be in compliance with the 2 under 2 rule - with those children. She can't take on any more.
Make sense?
