Talk with her. It's where Dad and I cook. This is the bathroom, where we take showers. And so on. You might feel silly.
Many new parents are shy when they first start to have a dialogue with their baby.
Practice, and you'll be amazed at how easy it becomes. Just try to remember that this is a little human being in your arms, a person whose senses are alive, a tiny being who already knows your voice and even what you smell like. While you're walking around, have Dad or Grandma make chamomile tea or another calming beverage. Tea, naturally, is my favorite. Where I come from, the moment a mum gets home, Nelly from next door nips over and puts on a kettle.
