It is very common for a newborn at that age to go thru a dry spell. It can last for more than a few days. As long as he does not look uncomfortable or straining, don't worry about it. DO NOT give a suppository without consulting your doctor.

Some moms have luck bicycling their babies' legs or just using a rectal thermometer. If you are still concerned contact your pedi.

I will suggest dropping the formula and getting him on a breastmilk-only baseline. First, breastmilk is a natural laxative while formula can constipate. Also, the bottles can interfere with your supply.
