i got DD1 done at 4months and to my surprose not a single tear just a little grizzle and that was it. I have had some ppl tell me that in their opinion its a form of child abuse but personally i would rather do it whilst they are younger. With DD2 (who is 8 wks) i will prob do it b4 she is a yr too. We never had any infetions or probs with them etc.
