Any store brand diaper should do unless you have blow out problems. Then I would clip coupons and watch for sales on brand name diapers. Personally, I have a disposable diaper service through Amazon. They ship a box of Huggies to me every two months for 15% off and free shipping. I have the option of skipping a shipment every once in a while if we don't go through them quick enough and still getting to keep the discounts. I use disposables because my son attends the public elementary school special education program but we use cloth everywhere else. He is going to be 4 years old in August. HTH!
