How to bathe baby

Hi mummies, how exactly do you give your baby a bathe. Normally i would just use normal bathtub and fill with warm water with 1-2 squeeze of mustela cleansing gel. Afterwhich i would soak his body in the tub and bathe him as per normal then dry him up with towel. Since im using soap, do i need to rinse him again with plain water ? #firsttimemom #advicepls
