Need advice.

I'm at stay at home mom right now with a 1 year old and I'm 24 weeks pregnant. I was a very active person up until and even after i found out i was pregnant again. Now it's freezing outside and I live in a very small place and i can't afford excercise equipment, nor a gym.

Ive gained weight during this pregnancy and it's very hard on me. What should i do? What can i eat that would be good for me to snack on? I don't like big meals. I'm 5'4 155lbs at 24 weeks pregnant. I was about 140ish before this pregnancy and 135 before i had my son. And does anyone know of any good double strollers for jogging? I'd love to get one for after i give birth.
