For the most part, your baby should be able to do certain things at a certain age, and it's important that he/she is meeting development milestones. Some children will be slower, some will be faster, but there are certain basic guidelines — what most children can do at a certain age — used by doctors that will guide both doctor and parent on the child's progress.
