Gabbi gets measured everytime she goes for a checkup. We always double check the length when we get home as the nurse as an old village lady who maybe needs new glasses!! They have a box they put her in, head up to the top and there's a measure on the side of the box. She puts a piece of wood at her feet and measures from there. But she got it wrong once, well either that or Gabbi had a major growth spurt! She went from growing approx 1 cm each month to growing 6 cm!! Now nursey said only 1 cm but we measured her when we got home, in fact we checked it 4 or 5 times and sure enough, the ruler said 62 cm NOT 57!!!!!!! Erm bit different.
ANYWAY, waffle waffle, we lay her on the floor, put a book at the top of her head, measure down to her heel, this is the measurement. Just do it yourself. I printed out a table so I cna chart her growth, you could also print out a percentile chart, just for your records. I love seeing her monthly growth. You could also do her head circumference.
He seems to be a long baby.
