Hi Lillypilly, don't stress, i'm 33wks and bubba has been having hiccups several times a day since about the 24wk mark. It freaked me out at first as i feared the worst, but the midwife was totally cool with it, said it's common and a good sign. Bubba's lungs are developing and just swallowing down the wrong tube! She said it won't do her (am having a girl!) any harm, it can just get a little uncomfortable for us given it's our belly their jumping around in! I'm trying to enjoy them as a sign that bubs is doing well.
