Have you ever wanted to be something other than human? Mermaids, half human, half fish, are one of the most amazing mythical creatures. Best known for sitting on rocks, singing, combing their long, blonde, beautiful hair. Their tail's color is based on the mermaid's personality, and reflects their true feelings. Pretty cool, huh?
Every baby is different, but most will roll over at an age between 4 months and 6 months. Rolling from front to back can be done just by kicking, which babies are pretty good at by that age, but going from back to front requires a little more upper-body (neck, arm, etc) muscle development.
Once baby can lift her head while on her stomach, she's almost ready to roll. By her fifth month, your little one will use her arms to push off, and with some effort she'll start to roll from her stomach to her side. Tummy-to-side rolling is common for babies because they can use their arms and legs to gain momentum.
