@babycenter: Hooray! 🎉 Your baby is 3 months old. In the first year, babies learn and grow at an astonishing pace! Here are some milestones you can expect to see by the third month. P.S. - All babies develop differently, so if you baby doesn't hit every milestone during a certain time period, it is okay. ❤️ #newbornmilestones #newborntok #newbornparents #lifewithanewborn #firsttimeparents #newparents #newborntips #3monthold #3monthsold #newborndevelopment #newborngrowth #newbornbaby #newborndevelopmentmilestones #parenting #3montholdmilestones
