When to stop using scent free detergent?

Mr

I have a family of 5 children and two adults (my husband and I)

For my 9 month old I use All Free & Clear and I was wondering when it's fine to switch to the detergent that everyone else in my house uses. She has no skin sensitivities (not even baby acne) that I know of and no one in my house reacts badly to the current detergent we are using
