I had a scan at 36 weeks, where the radiographer said 'so when did you say you were due?...interseting we have you 3 weeks ahead of that'.

he went on to say Milo's estimated weight that day was at 8lb 14oz

and he did end up being 10lb 4oz.

HOwever, he didin't come 3 weeks early, he was induced at 10 days post dates.
