When my daughter was having her son she showed signs of premature labor. Apparently a possible problem if you have asthma. They put her on something that she had to take every 6? hours. So her and her husband started the lack of sleep bit several weeks early. IIRC she was on it for a month which is as long as they will use it. They also gave her something that speeds up lung development which is the biggest problem in premies usually. Has him almost a month early and he was fine, went right home.
