Ivory snow laundry detergent?

j
The time to wash my baby's clothes before his arrival has come! After speaking to a friend, I decided to purchase Ivory Snow as per her recommendation. However, now I am concerned with how scented it is! It seems to be very heavily perfumed so I'm worried this will be too much. I was considering using Tide Free and Gentle instead. I can't return the Ivory, so I was wondering if it'd be safe to mix the two detergents? Using 3/4 Tide and then 1/4 of the Ivory for that SLIIIIGHT scent? If anyone has any experience with this or either of the detergents individually please let me know! Thanks :)
