i want to get hand/feet prints of my baby framed, what kind of colours can i use?

At that age kids tend to put everything in their mouth. So i would recommend making your own edible non toxic paint and using that. You can find recipes here: http://www.learnplayimagine.com/2013/03/homemade-paint-recipes-safe-for-babies.html This way you don't compromise on the colour or the safety of your child.
