The most common developmental problem a premature baby will face is developmental delay. So your doctor may ask you questions in the four domains of development that we think about. The first being gross motor. Those are the large motor movements like sitting or crawling. The fine motor movements like the way they use their fingers to maybe pick up Cheerios or small bits of food. The third being language. So how your baby is making sounds or responding to sounds. The fourth would be problem-solving. So that would be something like turning a cup upside down to get something out instead of reaching in to get it or dropping something on the floor and looking to see where it went. So we judge development based on the time that your baby was supposed to be born, so closer to the day that they were supposed to be born. So say your baby was 2 months early and you're at the 6-month check up with your doctor. We would be asking developmental milestones for a 4-month old rather than a 6-month old. If you're baby isn't catching up somewhere during the first and second year, we might suggest a full developmental evaluation with a specialist and perhaps developmental therapy.
