Ok everybody, the newbie here. I need please a FULL EXPLANATION, exactly, what is pipping, and what is zipping? Have babies due the 18th, 19th, and 20th and want to know EXACTLY what to watch for. I THINK I know what lockdown is, so when do I want to raise my humidity (I think the 16th?)and, shouldn't it be raised to about 70%?. Thanks so much for your help!!!
