I would say they take the pee, but I'd by lying. (Anthony suggested that line!) We used the Baby Dry range and they just aren't absorbent enough for Marianna's frequent and hard core bladder emptying. On numerous mornings I found the nappies had wet through, which isn't nice for me and certainly isn't nice for her. The adhesive strips didn't seem overly strong either, which was a contributing factor to other accidents...
There really is no contest.
