Books, charts, articles, podcasts, doctors, teachers, in-laws, etc. Everyone has a thought on what your child should be doing developmentally. And there are standard developmental milestones that researchers have coordinated to a specific timeline.
Every child is different. Each child grows differently. So instead of focusing on what your child isn’t doing, focus on what they ARE doing. By supporting and praising what your child CAN do, other areas will develop as well.
