When I was pregnant with Charlie I had an an ultrasound at around 35 weeks as it was suspected that my baby was "huge" and the scan calculations reckoned he would turn out to be an 11lber.

Based on this info (and the fact that Olivia presented with shoulder distocia during her birth) I opted for an induction.

Never again!

I have no issues with 3rd tri scans, but if it is about size predictions/a prompter to induce, I would avoid one, all the hocus pocus given by the calculations re size: to my mind it is just a crock! (Charlie was born at 6lb 13oz, so in no way was he huge at all: the calculations were, quite simply, wrong.)
