labor + delivery nurse OR ultrasound technician??

hi! so i want to have a job helping children, but i don't think i want to be a teacher, because to my knowledge, they don't make a lot of money, but i'm considering becoming a labor + delivery nurse or an ultrasound technician

i'm also bilingual and i might think about working with refugees as a medical interpreter, or doing something travel-based/international

would these careers bring a decent income, how long would i be in school/college for these careers??

(i live in the usa)
