Yes its normal. The licking and sleeping a bit more (for Meka anyway). You might even see her "hump" something and that too is normal. It can last anywhere from 2-3 wks. I'll only put a diaper on her if we are going somewhere or if it seems like shes spotting a lot, other than that I let her clean herself and do her thing... I also try to keep a lil diary of those things. Good luck
