Well, I have read the answers on here and am in agreement in most ways. I have had two experiences now, one before i finished my degree teaching in a daycare/preschool and now, with my bachelors in elementary education and early childhood, teaching preschool for Head Start/Pre-K Counts (run by head start, still employed by head start, different name).
working in day care-
lots of fun...little pay. no benefits.12 sick days, 12 vacation days a year. but it really was fun. i did it for about 1 year while i was still in school and it's fun to see some of those kids now. it is very rewarding and yes, i agree with those who mention the pros and cons above.
working for head start-
WAY BETTER! i am salary, with benefits, i stretch my pay check out so i get paid year round, more job security and *hopefully* my foot in the door to working in a public school. i'm on the same work schedule as my daughter- same days off, summer off...just like public school teachers. preschool is such an amazing age to teach because of the growth you see in just one year! i seriously love my job and love my partner (that makes a big difference, too). i feel secure in knowing that i have health insurance and will be starting the retirement plan next year. we get 10 sick days a year (for working 9.5 months, that's not bad). but realistically speaking, it doesn't pay well. i make $24,000 a year with my bachelors and i graduated with honors and am certified to teach through grade 6.
however, my point of telling you all this is that yes you can have a job in preschool with health insurance, retirement, sick days, summers off, etc... you can't do that in a day care. if you can afford it, it is a very rewarding job.
i advise that you get a double major in early childhood education and elementary education. this will make you more marketable and in the future, you might wish to work in Kindergarten-3 (still considered early childhood).
good luck! it's great to see someone who is excited about early childhood going into the field!
