My daughter reacts so weird !!!

Hello mommies!!!

My elder daughter August 2017 baby has too much possessiveness after her 3 weeks old sister is born which is common.. but she reacts so weird like getting irritated quickly.. today she wanted to lick my face n since I dint allow her she became so rebellious and forced herself to lick my face n started crying .. though I feel bad her n starts consoling her the most.. But dono y she got the licking habits.. she does only on my face..

Any of u mommies has faced this kinda behaviour in elder kids ??

Kindly help how to change this behaviour of hers !!

Tia !!!
