Weighting the baby

Probably a dumb question but out of curiosity what is the reason that sand is a no no for weighting your baby???

thank you for the quick reply!!! I was just curious since it is so much more cost efficient!!! I had used pool filter sand in the keeper for my daughter,and was curious what might happen I was hoping it was just because of shipping reasons.

I had been using sterile craft sand that is available at AC Moore and Hobby lobby and never had a problem with it. I have also shipped to UK and Australia and Saudi Arabia with no issues.
