You will probably want some wraps or light blankets to use as wraps at first. My son went into sleeping bags at I think 2 weeks but before that we just wrapped him in blankets. He kicked everything off. Now that it's warmer I've taken him out of the sleeping bags & just throw a blanket on him so he can toss it off if he gets too warm, but when the colder weather comes the sleeping bags will come back out.
