Hi,
I used it with my first baby, he was big, 9 pound 1! I needed a few stitches but not many, surprised i didnt tear more , looking at the size of him when he came out! Dont know if it helped at all, as my pushing stage was 2.5 hours, so naturally I was stretching anyway! Think i will use it again this time though, although hopefully my son well and truely paved the way!
