For a home daycare - 5 - that's it - 5 - simple. No matter how many adults - 5.

If you are licenced with an agency there are age restrictions so check with them, but if you are self-employed and running your own daycare with your own rules and contract then you can have 5 children of any age below 10 years of age.

If you are talking about a centre, sorry I can't help.
