Usually urine smells for one of two reasons: 1.) There is an infection of the urinary tract, bladder or kidneys. But that usually presents with other symptoms of crying and fever. The second reason could be concentration. If the babe isn't drinking enough fluids, the concentration of urine is stronger. Make sure that he's drinking enough breast milk formula and has access or you offer water throughout your day.
You also answered your own question when admitting that " I know I don't drink nearly enough water in my day" -- everything that comes out of the body of a breastfed baby is directly related to what YOU are , or are not, consuming! You need to drink MUCH MORE liquid, and that's not just water: milk is very important for calcium for both you and your baby, and orange juice is still also very healthy for you and the baby with the vitamin c and folic acid.
You might notice if there are any certain times when this happens - is it always just in the morning after a long night? After a certain food?
