Today Becca had another check up.
Apparently young Martin is a little on the small side (unlike it's parents then) and where Becca's stomach (also known as the baby size) measures 30 cm, 'Danger' should be in line with the number of weeks, around 32cm. So, the youth is about 2cms smaller than would be expected. Apparently there is nothing to worry about but if there is not more growth in two weeks time then a trip to the hospital will be in order.
Don't worry yourself too much. I remember the guy that used to sit next to me at work was so worried as the midwife kept going on how small their baby was and wasn't growing properly. Turned out it was just lying at a funny angle (round the way I think) and so the measurements were small and she was quite a susbtantial baby once born, epsecially considering how tiny the mum was. All that worry for nothing.
Take care of yourselves.
Eilidh.
