The vagina can feel looser, softer and more 'open' and looks and feel bruised or swollen. However, the swelling and openness should start to reduce a few days after your baby's born. You may do pelvic floor exercises to tone the vaginal muscles. How you do it is:
squeeze and draw in your anus at the same time, and close up and draw your vagina upwards
do it quickly, tightening and releasing the muscles immediately
then do it slowly, holding the contractions for as long as you can, but no more than 10 seconds, before you relax
repeat each exercise 10 times, 4 to 6 times a day
