Yes, I've seen it.... that's why I have one now
The fc it totally cute b/c of the butt cheek thing
My big girls cheeks were hanging out of her Tykies today and I just smiled.
I'm diapering a 7 mos. old and a 26 mos. old so I see a range of the fit. My girls have some junk in the trunk so I think I'll try the reg. for fun. SB are snuggly diapers and the fc is so nice - we have big thighs too.
