You've got it the wrong way around, really.
Your contract is a written record of the agreement you've made with the company you do work for. It tells you what you've agreed you'll do, how you'll do it and what they'll give you in return.
If your contract allows you to do your job any way you like as long as you do it, and you only get paid for what you've done, then you're probably freelance.
If your contract says you'll work certain hours, or so many hours per week, or certain days of the week, then that's what you must do and you're very likely to be employed even if they call you freelance.
You need to look at your contract and see what you've agreed to do.
I have to say that this job sounds like a complete non-starter. Generous commission only pay structures are only generous if you get the lead that qualifies for payment. The rest of your time is dead time. You will lose huge amounts of money in childcare before you make any money.
Do something with a wage to get your CV off the ground.
