Long stay France visa for minors

My wife and I have Long Stay Visa in the “entrepreneur / profession libérale” category from France, and already rented a house in Paris to live.

Two weeks ago our baby girl was born in Canada, and now we are planning to return to Paris in 6 weeks, I was wondering should we request a visa for our newborn baby? Or we should just go to Paris (She needs no visa for entry and staying for 90 days) or what?

I am not sure what should we do, Please let me know if anyone knows what to do.
