newborn crochet measurement help!?

i am crochet a few newborn items for a friends baby photo shoot. i will be making newborn hats, diaper covers, cocoon, and hammock. i am having a hard time finding correct measurement for these items online. can anyone help?! greatly appreciated!

I found a site that has a lot of measurements for babies on it. Hopefully you’ll find it helpful: http://www.bevscountrycottage.com/size-chart.html

Good luck and have fun!
