When my daughter was born, my son was a toddler. Like most 3 year olds, he was always getting into things, especially when I was busy feeding or changing the baby. I remember raising my voice often to call out to him or get his attention from another room while holding my daughter in my arms. She would jump and sometimes cry at the sound of my voice. As a parent, you might have unintentional habits that make your baby think your angry because they're still too little to understand the world around them.
According to the website for Parenting, babies know their mom's voice before birth, somewhere around seven months gestation. This means that by the time you give birth, your little one already knows who you are just by the sound of your speaking voice. Baby Center noted that research done at the Pacific Lutheran University found that unborn babies actively listen to their mothers in the womb during the last 10 weeks of pregnancy. Your baby knows you, but it will take time for them to learn the nuances of language and facial expressions. In the meantime, your baby may mistake these five everyday habits as signs that you're angry.
