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.
These movements are necessary for rolling over and crawling. By the end of this period, babies should be able to roll over from stomach to back and back to stomach and probably are able to sit without any support. By age 4 months, babies can easily bring toys to their mouth. They use their fingers and thumb in a claw-like grip to pick up objects. Because at this age babies will instinctively explore objects by putting them in their mouths, it is important to keep small objects out of reach to prevent accidental swallowing.
