Splashes from the sink

Salaam, 1. If I wipe my newborn child with wet wipes after defaecation or urination, and then wash the private parts with water in the sink, are the splashes which fall back on me and my clothes Najis? 2. when the child is born, the nurses just wipe the blood with a towel. When I m going to bath the baby ( after some days ) are the splashes which fall back on me Najis? I would like to know if there are differences in the opinions among the scholars? I would like to choose an easy way to relief myself. Thank you!
