I use it for the whole family because my husband and 5yr old have sensitive skin

yes you can....I will however recommend a free and clear detergent. Even baby detergents have scents that can cause irritation. I love purex free and clear. It's about $4 for 50 loads

I use dreft & all the clear sensitive kind. I think reg is too strong for baby

I use all free and clear for my son clothes and regular for mine but he has sensitive skin and will break out if I used anything else

I do for my baby
