How to measure a baby...again

Today was a write of. Cam had a sleepless night as his teeth were giving him real issues. We can count on one hand the amount of times cam has been up at night since he started sleeping through at 10 weeks old so it is always an indication that he is really really bad! So that coupled with ollie's feeds meant no one really slept so the day was spent relaxing and only venturing out for cam's swimming lesson.
The only use the bed had was for using it to help determine ollie's length. We did the same with cam when he was a similar age and we have determined that Ollie is longer then cam was. Everyone will tower over mummy in a few years at this rate!
