I get sick, feel tired. so my body soft is incorrect and does not make sense here. You can not translate 软绵绵 as soft here. Instead you should translate it as 'weak' I am sick and feel tired. so my body is weak. the bady borned a few days touched softly? I'm sorry this sentence makes no sense at all. From your Chinese I can see you want to talk about what a new born baby feels like yes? Here you can translate 软绵绵 as soft. A newborn baby's skin is soft (and smooth as silk).
