Re: I need help with leaky diapers! :(
Like others I too think you're having absorbency issues.
Somewhere around 5-6 months of age I had to switch to fitteds & wool at night. Before my LOs were 1 we needed to use night time fitteds. Shortly after they turned 1 we started using night time sposies because they could not toddle around comfortably in their other night time bulk. For about a month or two we needed to put wool over a night time sposie but that phase soon ended.
