I had the same problem downstairs after I had bub #2. I was thinking the worst and getting very upset at the thought of no more babies. I was holding it all in and getting more and more worked up til one day I blurted it out to my mum (expecting her to be all concerned for me!) and she said "oh don't worry about that, it's nothing. I had it after every baby and it all goes back to normal"... She's had 5 babies. So that made me feel better! Sure enough everything downstairs is back to normal! It takes some time (and pelvic floor exercises help too) but you'll get there. Hugs x
