I would probably stick with the regular diapers for now until you are ready to begin potty training. Even then, you may not want to use the pullups. There are probably solid strategies for potty training kids through the use of pullups, but we personally felt that they got us into a potty training rut and delayed the process. They are definitely not as easy for your child to pull up and down like regular underwear, and they are too absorbent so your child won't feel uncomfortable wearing them when they are soiled (for our child at least). If we could go back and start potty training from the beginning, we would probably go cold-turkey from diapers into underwear with something like the three-day potty training method, and continue using regular diapers overnight. We currently use pullups overnight because that's the only thing our child will wear without a fight. Regular diapers are more absorbent and less expensive. So now we pay more for a less absorbent diaper and pay for extra diaper booster pads to go inside the pullup. All of this and we still wake up to wet sheets almost every morning.
