Q. When do you stop describing your baby's age in weeks and start using months? For example, should I say that my baby is eight weeks or two months old?
In general, most parents use weeks until it becomes too confusing.For example, people usually know exactly what you mean when you say that your baby is six, eight, or even 10 weeks old. It gets a little confusing when you say that your baby is 14, 18, or 20 weeks old though.
However, using weeks versus months is really just a personal preference.
Keep in mind that your pediatrician may use weeks until your baby is two to three months old. Using weeks allows your pediatrician to be more precise in choosing medical therapies when your baby is sick.
