Baby laundry detergent - what to buy?

Diana • TTC #1 successful May 2016, thanks to Glow
Hi, I'm 6 weeks with my first so I'm assuming I can't just use regular detergent to wash baby textiles (unless anyone wants to share that they have and their baby hasn't had any bad reaction?). 
What do I get? I've heard of Snow, Dapple (is that for washing bottles or also for clothes?) and some fancy schmancy stuff that comes with different cloth diapers (I forget the names). 
They all seem more expensive than regular detergent but should I just splurge or should I get the something minimally higher than the regular detergent?
