Sticking tongue out

Gi

My 3 month old started sticking her tongue out today after nursing... not the mimicking kind where it peeks out.... like open mouth and her whole darn tongue.. I tried to catch a picture this last time, but couldn't lol. I thought maybe she was still hungry. Tried giving her the boob. She was disinterested lol. She did it multiple times today and all after feeding....

Anyone else's LO do this and know if it means anything ..?
