Should you be concerned if your baby is not meeting her developmental milestones on time? For the most part, the answer is yes. While there is a time range for baby development that is considered normal, if your baby does not meet those time frames, you should take action. I'll tell you why. Babies are born with billions of neurons. Not all of them are activated, and many will "die off". There is a window of opportuntiy during development that is ciritcal for preserving some skills, One that everyone can relate to is language. Babies are born with the capacity to distinguish between sounds for all spoken language. By the age of about 11 months, they only distinguish sounds of their native language. This will give you an idea of why it's so easy for a baby to speak two languages if they are raised in a bi-lingual home.
Another important consideration is that motor skill development and cognitive development go hand in hand. When a baby kicks a toy in her crib and it starts, it is random at first. As it happens more often, she begins to make the association between kicking and the toy activating. She is learning cause and effect. If she is not moving, this learning does not take place as well.
It is not possible to know what skills your child will miss out on if she is not meeting her milestones. And she may be fine. But imagine the potential she had that wasn't preserved because of her delayed development. As a parent, I want to do everything I can to ensure my son reaches his potential. I am sure you do too.
