You wanted to know when your baby is going to smile for the first time. And most babies have done this by the time they're 6 to 8 weeks of age. And it is so rewarding, and fun, and exciting when your baby smiles at you for the first time, and when they begin laughing and responding to you. They can actually tell that your voice is your voice by the time they're 1 month of age. If they're in the same room with you, but not being held by you, and they hear you, their little head may turn, because they recognize you as you. Babies actually come primed to socialize with us. They love it. They would much rather see your face and hear your voice than see an object or hear any other noise. And the more you interact socially with them, the better they're going to be at interacting with you and likely, the sooner you're going to see it happen. We all get that funny, silly, high-pitched voice when we're talking to babies (some people call it baby talk) and there's a reason for that. Babies are really into that. They're really into facial expressions and fluctuations in our voice. And even though they can't talk, you should talk to them and give them a second to respond back. It's not going to be words in the beginning. They may just look at you and have a blank stare, but eventually, they'll smile at you. And as they get older, they'll begin cooing, and coos will turn into actual language. They also love to mimic you, so if you stick out your tongue, they're going to try to stick their tongue out, or if you open your mouth wide, they're going to do the same thing. They are just soaking in everything around them, including interactions that you have with them, and that teaches them how to interact with you and others. All babies do develop at slightly different rates, and so if you ever have concerns about your baby's development, whether the milestones that you're concerned about are physical, cognitive, social, whatever they might be, talk with your pediatrician. And after asking more specific questions and interacting with your baby one on one, they'll be able to give you tailored information and advice. If you have more questions in the future for me, feel free to ask them at Intermountain Moms on either our Facebook or Instagram pages, and recommend us to your friends and family too.
