teacher probs


so I taught 4th and 5th grade before taking two years off when I had my twins. then I joined the world of early childhood for a year and a half, because I feared the time commitment of teaching. then I got crazy and took a teaching job for this school year and a week later I found out we are pregnant. now, I'm worried I won't be able to handle my first year back with two kids and being pregnant. plus, I'm nervous about talking to my new principal about maternity leave. advice or encouragement please.
