Laundry detergent opinions!

Jasmin
Hey ladies, so I'm a first time mommy, currently 31 weeks pregnant.i wanted your opinions on baby laundry detergent. I'm on a budget. My sisters keep saying I cannot wash any baby items with regular Tide, that I must buy special baby detergent. I personally think it's the same thing. What have you other mommies done? Please help thanks :)
