How to Measure Your Hip SizeHow to measure your body

WUKA TIP: No tape measure? 
You can measure yourself with a belt or dressing gown cord and a 30cm ruler! Tie the belt around your hips, place a piece of tape or pinch where it reaches, then lay flat and carefully use the ruler to measure the length.

I bought this for my daughter Lyra, 9 years old. She had started to grow some body hair and her body changing a bit and I really wanted to start helping her learn it’s ok and she can ask us anything. She adores the rebel girls series and when I saw this I just had to buy it, the first period conversation has been going on a lot so I wanted to help. Obviously my wife being the helpful one in that area and daddy just listening. My wife had never tried your pants so I have bought her a pair to try out, so she can then honestly answer any of my daughter’s questions about all different types of products. From a daddy just trying to stay involved and let his little girl know he loves her I can highly recommend this book and all it has to offer. Read it with them and help them grow up powerful.
