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.
What's next. Most of the muscles babies use for rolling over are also used for sitting up independently and crawling. As your baby's neck, back, legs, and arms continue to get stronger over the next few months, he'll soon be able to sit on his own and scoot around the house. Most babies have mastered sitting up by six or seven months; crawling comes a little later.
