Paint on baby skin

Can I use acrylic paint on my baby's feet for a very short period of time? I am a stay at home mom witj a 10 day old and wanted to do something inexpensive for Valentine's day for my hubby so I thought I could make Valentine's with my daughter's hand and footprints. I have a ton of acrylic paint I could use but I'm not sure if that would be safe of her little feet? If not any ideas of paint or ink that would? This is what I'm looking to do. Thanks!
