We just dropped DD down to 1 nap. She's 10.5 months. Well now she is STTN 13-14 hours. Which is awesome. But now she is peeing (yesterday a blowout too) through her diapers, jams and sheets. We CD during the day and so far have used Kirkland and Huggies overnight with the same result. She's at the low end for weight (17.5 lbs) for size 3s. Should we go up a size? Could you recommend another brand?
