Career choice

I am 21 a stay at home mom to both my babies, my husband is the bread winner..I want to get into school but i don't know what for I wanted to be a prental sonogram technicain but i was reading online, all i see is how it's hard to get a job after you graduate.. I want a job working with kids babies anything to do with children... That doesn't require a whole lot of schooling? Please help! I love the idea of wearing scrubs to work everyday as well! Thank you ladies so much!!!

Edit : I was going to look into grants and financial aid.. I also have family willing to help.
