Side sleeping causing pee leakage...

Al
So my lo is 6 1/2 months old & has recently started turning on her side while sleeping. My issue is that her diaper doesn't hold her pee & she wakes drenched & pissed off. We use Huggies Little Movers & haven't had a single complaint until now. So I guess what I'm wondering is has anyone else had this issue & if so what did you do? Is there an alternative to regular diapers that work better so our sweet side sleeper can go back to sleeping peacefully through the night?
