Just weird

My 6 weeks LO always so calm when outside. Today we went for dinner at hotel and she cried murder unable to coax. It was so hard to calm her down during dinner. She was fine after we make our way home. But kept wanting milk. Finished 60ml on the journey back(which as quite short) and breastfeed both breast when came home. And 2 times of wet diapers just after reach home
