Only you can answer this for yourself ~ my answer is no because it is 'illegal' and that's the bottom line for me ~ I do not have to 'agree' with the ratio rules or not cause that is irrelevant.
Ask yourself ~ if someone were to 'notice' and report you would the 'benefit' of this arrangement to your family be worth the fact that you could potentially be faced with a fine of $2000 a day for every day you were found to be over ratio operating an illegal daycare by the Ministry of Education?
Or that if the client or their child was 'injured' during this time frame you were 'over ratio and illegal' and as a result of that injury were wanting compensation would the 'benefit' of this arrangement out weight the fact that your home childcare ryder insurance would be void as a result of being illegal and over ratio and your home insurance policy would not cover it because it was 'business' related and not home ~ so you could be paying 1000's of $ in medical bills and potential being 'sued' because you know even though they might play ignorant when its too their advantage the minute it is 'not' they will plead they did not know you were illegal and you took advantage and so forth ~ people exploit that to their advantage!
Will you share this 'change in program policy' with your current clients or hope they do not notice ~ the risk being that either way if you tell them directly or they 'notice' some of them might be uncomfortable and 'pull' .... is the benefit of this arrangement worth that risk of loss of income from your full time clients?
These are the 'risks' you take with breaking the rules ~ if you weigh them and are fine with that it is personal choice!
