My 19 month old uses the size 5 during the day and size 6 during the night. I have found the quality to be similar or the same as store-bought nappies. I have been using the subscribe and save from Amazon since she was born and I have never had an issue with the quality being less than store-bought. That being said, I have recently switched her night nappy to the Huggies Ultimate Nappy Pants because I was finding that she had started to leap through the Huggies ultra-dry and her pajamas and sleepsuit are quite wet and smelling of urine by the morning. She wears her night nappy for about 12-13 hours. Since switching I have had no night leaks. Definitely would recommend for a day nappy, not sure it stands up to the 12-hour leakproof promise though for a night nappy.
