My BFF was completely negative abt CDing when I was pregnant with my first and I was talking abt it. She said she had tried it before when her sister far her some diapers and it was worthless (se had some cheapy prefolds and covers from gerber). Not long after I had my LO was she CDing too! I still give her a hard time abt it :-p
Hang in there bc this is just one of the many things you will get negative remarks from family and friends. Ppl are very vocal abt their opinions anymore whether you want to hear it or not.
