2 or 3 year old not leaving mommy alone before labour??

Can a 2 or 3 year old can know or smell or something when labour is coming? My 2 and a half year old daugther is been very mommy for everything for 2 weeks now, but today, is been insane, more than never before. I have my scheduled csection for Friday June 14th, but been feeling very off since yesterday, and my daugther today doesnt want to leave me alone at all, kissing my belly all the time, giving me cuddles all the time, hugging me, doesnt want to be with anybody else. Could this be that she knows or sense that maybe labour is very near?
