when should premature baby start tracking
Preemie Milestones in Development. Note: The information below shows how young children typically develop. It is important to use your childâs adjusted age when tracking his development. So, if your baby is 21 weeks old, but was born 5 weeks early, his adjusted age is 16 weeks (or 4 months). This means you should refer to the milestones listed under âat 4 months (16 weeks)â to see what your child should be doing at this age.
