Most children do not start speaking words and formulating sentences until 18 months to 2 years of age. Before this development, they rely on crying to communicate their wants and needs to their mothers. Unfortunately, there is no high-tech translator that can help you talk to your baby; you must find out over time to understand your child — in essence, you have to learn a second language. According to professor Alison Gopnik of the University of California, Berkley, “looking at what [babies] do, where they look, what interests or bores them can tell you a lot." As a new mother, it may seem impossible to tell the difference between a tired cry and a hungry cry, but fear not! Being around your baby and doting on them for all hours of the day means you will pick up on the signals they are sending you; you will eventually become “bilingual.”
