I have nine size 1 kissaluvs for Zac. I didn't bother with any size 0. He was 8lb 13oz so the size 1 fit him after only two weeks. I love the coloured ones. I found the drying time Ok, no worse than a diddy diaper and faster than a bamboozle. The absorbancy has been fine so far for daytime lasting about 3 hours.
The only prob has just developed and that is they are now to short in the rise. He's only 14lb and there is plently of room on the waist but he had a serious builders bum. I think he must be quite a long baby as I've also had this problem with Tots Bots size 1.
Don't know whether that rambling helped or not!
