As the baby gets bigger your spine is pulled in to a more arched position so:
1) In the last trimester (3 months) try to occasionally lie down with knees bent and feet flat; flatten your spine slightly towards the floor/bed.
2) Roll your knees from side to side gently whilst in this position.
3) Resting with knees and ankles supported up at right angles: try lying on floor with calves supported on the sofa.
Try to avoid standing still; either move about or raise yourself up and down on your toes to encourage circulation and prevent varicose veins. When turning over in bed:
try and keep your knees together as you ’inch’ over bit by bit, lifting your bottom only a small amount at a time. When turning over in bed:
NEVER sit straight up; always roll to one side and lower legs whilst pushing on your hands.
