Recommend diapers with no leakage for 18mth old?

Hi my LO is 18mth old and has been using Goon till 16mths no leakage and no rashes when she kept pulling at the waistband of XXL and then I changed to Merries XL. But I’m facing issues with Merries as it keeps leaking even for daytime naps. I’m not sure if it’s the position or what it is? Can you recommend any diapers that will not leak and good for sensitive skin that will not cause rashes? Thank you!
